## How do you use Avogadro’s number to find mass?

Using the same method, you can determine that there are 0.5551 moles of oxygen also present. Multiply the number of moles of each element by that element’s molar mass. This gives you the total mass of each element in your sample. For example, 1.102 * 1.0079 = 1.111 grams of hydrogen.

## What is the formula for Avogadro’s law?

Where “V” is the volume of the gas, “n” is the amount of the gas (number of moles of the gas) and “k” is a constant for a given pressure and temperature. In fact, Avogadro’s Law, the hypothesis set by him, was among the laws on which the Ideal Gas Law is based.

## How many grams are in Avogadro’s number?

Avogadro’s number. Avogadro’s number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 1023. The units may be electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction (if any). See alsoAvogadro’s law.
