For every mole of H2SO4 molecules, there are 4 moles of oxygen atoms, which has a molar mass of 16.00 g/mol (mass of the part): Now we just punch in the numbers and find: Now we can do the same for the other two compounds!

## How many moles of oxygen atoms are present in 1 mole of H2SO4?

H_{2}SO_{4}: 4 moles of oxygen are present in 1 mole of H_{2}SO_{4}.

## How many moles of oxygen are present in 5 moles of H2SO4?

Or. 5 mole of H2SO4 contains 20 atoms of O.

## What is the mass of O in one mole of H2SO4?

Solution — 1 molecule of O2 = 2 oxygen atoms So, 1 mole of O2 = 2 mole oxygen atoms = 2 × 6.022 × 1023 = 12.044 ×1023 oxygen atoms.

## How many moles of oxygen atoms are there in 1 mole of oxygen molecule Brainly?

One mole of oxygen gas, which has the formula O_{2}, has a mass of 32 g and contains 6.02 X 10^{23} molecules of oxygen but 12.04 X 10^{23} (2 X 6.02 X 10^{23}) atoms, because each molecule of oxygen contains two oxygen atoms.
