# Frequent question: What is the mass of 2 moles of lithium?

Contents

Based on the chemical formula, we have 2 atoms of Li, so the atomic weight of Li has to be multiplied by 2 to obtain 13.88 g/mol.

## What is the mass of one mole of lithium?

Lithium for instance has an atomic mass of 6.941 grams and this is equal to one mole of lithium. This is why we state the atomic and molecular masses in units of grams per mole or g/mol. What can we do with moles?

## What is the mass of 2 moles of HgO?

The molar mass of HgO is 216.59g/mol. You can get that by adding the molar mass of Hg to the molar mass of O. So, two moles would be twice the molar mass of 1 mole of HgO. The mass of 2 moles of HgO is 433.18g.

## What is the mass of 5.40 moles of lithium?

Answer: The mass of lithium is 34.7 grams.

## Is Amu equal to g mol?

The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol). Although mass can be expressed as both amu and g/mol, g/mol is the most useful system of units for laboratory chemistry.

## What is the mass of one mole of H?

One MOLE of hydrogen atoms contains the same number of atoms as the number of hydrogen molecules in one MOLE of hydrogen molecules, i.e., Avagadros number. However, one mole of hydrogen atoms has a mass of 1 gram while one MOLE of hydrogen molecules has a mass of 2 grams.
