## How do you find the mass when given moles?

Multiply the number of moles of the substance by its molar mass in grams/mole (g/mol). The molar mass of calcium chloride is determined by multiplying the subscript for each element by its molar mass (atomic weight in g/mol), and adding the results. You can also look up the molar mass.

## What is the mass of a mole of an element?

The molar mass of a substance is the mass in grams of one mole of that substance. This mass is given by the atomic weight of the chemical unit that makes up that substance in atomic mass units (amu). For example, silver has an atomic weight of 107.8682 amu, so one mole of silver has a mass of 107.8682 grams.

## How do u calculate mass?

Mass is always constant for a body. One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.

## How do you find the mass of an element in a compound?

Now, mass of an element in a given mass of compound = (atomic mass of the element × number of atoms of the element in one molecule of the compound) × given mass of compound / molar mass of the compound.
