## How do you find moles when given molarity and volume?

Compute the volume of a solution in liters, given the number of moles and molarity, by dividing the number of moles by the molarity in units of moles per liter. For example, a solution containing 6.0 moles and a having a molarity of 3.0 moles per liter has a volume of 2.0 moles per liter.

## What does n m/m mean?

n = m/M n is the amount of substance, in moles, mol. m is the mass of the substance, in grams, g. M is the molar mass of the substance (the mass of one mole of the substance) in g mol-1. Molar masses: These. will be given in.

## Is molarity moles per liter?

Molarity is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution.

## What is the molarity calculator?

The molarity calculator is a useful tool which allows you to calculate the: mass of a compound required to prepare a solution of known volume and concentration. volume of solution required to dissolve a compound of known mass to a desired concentration.

## How do you find moles in an equation?

Divide the number of grams of each reactant by the number of grams per mole for that reactant. 50.0 g of Na are used in this reaction, and there are 22.990 g/mol. 50.0 ÷ 22.990 = 2.1749. 2.1749 moles of Na are used in this reaction.
