Question

the amount of S present in 1.5 mole of H2SO4 ?

Answer 1

Answer:

Avogadro's Number (named for Amadeo Carlo Avogadro 1776 – 1856) tells us that 1 mole contains 6.022 x 10^23 molecules. So, 1.5 moles contains 1.5x 6.022 x 10^23 = 9.033 x 10^23 molecules. Similarly, there are 9.033 atoms of sulfur, 3.6 x 10^24 atoms of oxygen.
