Question

Calculate the no. of atoms of hydrogen in 9.8 gram of H2SO4.(1.204×10²³H atoms).​

Answer 1

Explanation:

BY USING THE AVAGADROS CONSTANT:- 6.02 X 10^23,

NO.OF ATOMS = MOLES X AVAGADROS CONSTANT X NO.OF ATOMS

MOLES OF H2SO4 =9.8÷ 98 =0.1

0.1 x 6.02 x 10^23 x 7 (NO. OF ATOMS) =

4.21 X 10^23
