## How many moles are in 16 grams of O2?

Here, we are given with 16 g of oxygen. The number of molecules in 16 gm of oxygen are **0.5 (= 16/32 moles)**.

## How many moles are in a gram of oxygen?

Moles of a Substance and the Molecular Weight

The mass of oxygen equal to **one mole** of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.

## What is the value of one mole oxygen?

One mole of atoms of oxygen has a mass of **16 g**, as 16 is the atomic weight of oxygen, and contains 6.02 X 10^{23} atoms of oxygen.
