One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.
How many molecules are in 2.00 moles of oxygen gas?
So, 2moles of O2 contains 2× 6.023×10^23 molecule= 12.046 ×10^23 molecule .
How many atoms of oxygen are in 3 moles of oxygen?
A mole of anything contains 6.022×1023 individual items of that something. You have 3 moles, so there are 3×6.022×1023 oxygen molecules .
How many atoms are present in 2 moles?
If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.
How many atoms of oxygen are in 5 moles of oxygen?
Hence, number of moles of Oxygen in 5 Moles of CO = 5. The number of oxygen atoms present can be obtained by multiplying the moles of oxygen by Avogadro’s Number. So, number of oxygen atoms present = 5 x ( 6.023 x 10^23 ) = 30.115 x 10^23 nos.
