Contents

## How many atoms are there in 2 moles of oxygen molecules?

There are 6×6.022×1023 atoms in 2.00⋅mol NO2(g) .

## How many molecules are in 2.00 moles of oxygen gas?

According to the concept, 1 mole contains 6.023 ×10^23 particles. So, 2moles of O2 contains 2× 6.023×10^23 molecule= 12.046 ×10^23 molecule .

## What is the mass of 2 mole of water molecule?

If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.

## How many atoms are in 3 moles of oxygen?

1 mole of a substance there are 6.022*10^23 atoms/molecules. From this we can deduce that there are 3*6.022*10^23 O2 molecules in 3 moles.

## What is the mass of 4.00 moles of oxygen gas?

4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.

## How many moles of oxygen atoms O are present in 2.0 moles of oxygen gas O2?

How many moles of oxygen atoms are present in 2.0 g of oxygen O2? 1 mole of O2= 2 moles of O. So Moles of oxygen = 2 x 0.0625=0.13 moles of O.
