Question

How many moles of hydrogen atoms are there in 178 mL of 0.20 M H2SO4? Write your answer in
scientific notation.

Please help

Answer 1

You have mols H2SO4 = M x L = 0.178 x 0.2 = ?

Since there are 2 H atoms per 1 molecule H2SO4, then there will be twice as many H atoms as there are mols H2SO4.

Answer 2

so the answer for mols H2SO4 is 0.0356. So I have to

0.0356*2 atoms of H = 0.0712 atom of H

Am I correct?

Answer 3

yes
