URGENT PLS​

Answer 1

Answer:

120.44×10²³

Explanation:

One molecule of H2SO4 has 4 atoms of oxygen.

So, one mole of sulphuric acid will have 4 moles of oxygen. Therefore, 5 moles of sulphuric acid will have 4×5 = 20 moles of oxygen atoms.

One mole of any substance will have 6.022×10²³ particles of that substance. Hence, the total number of oxygen atoms in 5 moles of H2SO4 = 20×6.022×10²³ = 120.44×10²³ atoms.
