Chemists use equivalent units, or equivalents, to express the contribution of an acid or base to the total acidity or alkalinity of a solution. To calculate the pH of a solution--the measure of a solution's acidity--you need to know how many hydrogen ions are present in the solution.
In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass. First, you will need to calculate the molar mass of calcium bromide by using the periodic table and the number of each element in the formula. Now, use the number of ...
A milliequivalent (mEq) which is 1/1,000th of an equivalent, is a more common measure than equivalents because of the amounts in which substances occur in everyday chemistry situations, which is more often in milligrams than grams.
Lesson 6: Solutions of Acids & Bases . In this part of Lesson 6 we'll study some of the concepts you'll need to understand the technique of acid-base titration. An acid-base titration is a technique in which precisely measured volumes of acid and base solutions are mixed until the two just neutralize each other.
To convert moles into grams, determine the number of moles preset and the molar mass of the compound. Multiply the number of moles by the molar mass to obtain the final answer in grams. Determine the number of moles. The number of moles present in a compound is often given to the student in the problem.

Here are a couple of examples of mole-volume conversions. The first part shows you how to convert from 0.30mol of CO to liters of CO. The second part shows the conversion from 18.2L Ne to moles of Ne.
The mass and molarity of chemical compounds can be calculated based on the molar mass of the compound. The mass (in grams) of a compound is equal to its molarity (in moles) multiply its molar mass: grams = mole × molar mass.
the question asks... a solution containing the sulfate ion is 0.025 M. What is this concentration in Eq/L and mEq/L?
I just had a passage-based question from a Kaplan FL that required me to convert from milliequivalents (mEq) to grams. I guess there was an AAMC 9 question that inclued mEq so Kap created a question on it. But I was wondering: Is this something that any other test preps emphasize? Ps. mEq = mg x Valence / (molecular weight) 1.
We will use molar equivalents (eq) to compare the number of moles of different compounds. In the egg and toast example above, the ratio is 1 to 1, so we would say that there is 1 equivalent of eggs and 1 equivalent of toast. On the other hand, if you have 3 moles of compound A and 6 moles of

How to Convert Measurements Easily in Microsoft Excel. Excel's convert function ("=CONVERT()") converts a measurement from one unit to another. To use this function, you will enter data and units into the formula: =Convert(number,...
Knowing the molecular mass is necessary to convert grams to moles. Multiply the number of atoms each element contributes to the compound by the atomic weight of that element. Add the total weight of each element in the compound together. For example, (NH 4) 2 S has a molecular weight of (2 x 14.01) + (8 x 1.01) + (1 x 32.07) = 68.17 g/mol.
A frequent question arriving in my email mailbox is "how can I convert a volume to a weight?" Most commonly, people are trying to find out how to convert from liters to metric tons - often for substances such as water, gas and oil.
This molarity calculator is a tool for converting the mass concentration of any solution to molar concentration (or recalculating the grams per ml to moles). You can also calculate the mass of a substance needed to achieve a desired molarity.

Grams to Moles Calculator. Mole is a standard measurement of amount which is used to measure the number atoms (or) molecules. 1 mole of something is equal to 6.0221415x10 23 of it. This online unit converter will help you to convert the grams of a molecule to the number of moles based on the weight of given chemical equation / formula.
Molarity refers to the molar concentration of a solution, that is, the number of moles of solute dissolved in 1 liter of solution, as mol/L, abbreviated as M. Molarity Calculator Equation:
For chemistry you often need to convert moles to grams and grams to moles. There is a simple relation between these two:, where - mass of the substance in grams - quantity of the substance in moles - molar mass of the substance in grams/mole. And the most difficult task here is finding out the molar mass of the substance.
the difference of moles and equivalents on the reactants is simple. ... How to calculate equivalents (w/w) of a reagent? ... I don't know how much this answer will help to estimate or to convert ...
Use this page to learn how to convert between moles and millimoles. Type in your own numbers in the form to convert the units! ›› Quick conversion chart of moles to millimoles. 1 moles to millimoles = 1000 millimoles. 2 moles to millimoles = 2000 millimoles. 3 moles to millimoles = 3000 millimoles. 4 moles to millimoles = 4000 millimoles
Imagine that you have 100 moles total mixture, 15 moles styrene, 85 moles of the other monomer. The weights of the mixture components are 15 moles*104 g/mol = 1560 g styrene, and 85 moles * 54 g/mole = 4590 g of the other monomer. The total mixture is 1560 g + 4590 g = 6150 g, and the weight ratio of styrene to total mixture is 1560 g/6150 g ...
