Calculate the mass (in g) of oxygen in 3 moles of sulfuric acid molecules, H2SO4.

Sure, here are the steps to calculate the mass of oxygen in 3 moles of sulfuric acid (H2SO4):

1. First, we need to know the molecular formula of sulfuric acid which is H2SO4. This tells us that there are 4 atoms of oxygen in one molecule of sulfuric acid.

2. The molar mass of oxygen (O) is approximately 16 g/mol. Since there are 4 oxygen atoms in one molecule of sulfuric acid, the total mass contributed by oxygen in one mole of H2SO4 is 4 * 16 g/mol = 64 g/mol.

3. Now, we have 3 moles of H2SO4. Therefore, the total mass of oxygen in 3 moles of H2SO4 is 3 * 64 g/mol = 192 g.

So, the mass of oxygen in 3 moles of sulfuric acid is 192 grams.
