Get the mass in grams of methanol by multiplying its density by the given volume. Divide the mass in grams by the molecular weight in grams per mole. The result is the number of moles that you have in the given volume.

## How many moles are in methanol?

In one mole of methanol, there are 6 moles of atoms.

## How do you calculate the molar mass of methanol?

How to find moles?

## How do you find the mass of a mole?

The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

## How do you find the mole fraction?

Mole fraction (X_{solute}) = moles of solute / (moles of solute + moles of solvent) .

## How do you find the theoretical yield of a mole?

When you know the number of moles that you expect, you will multiply by the molar mass of the product to find the theoretical yield in grams. In this example, the molar mass of CO_{2} is about 44 g/mol. (Carbon’s molar mass is ~12 g/mol and oxygen’s is ~16 g/mol, so the total is 12 + 16 + 16 = 44.)

## How do you convert from moles to grams?

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.
