The number of hydrogen ions in 4.9 g of tetraoxosulphate (IV) acid is?

(S = 32, O =16, H = 1, Avogadro Number = 6.02 x 10\(^{23}\) )

M=2+32+64
M=98
n=4.8/98
n=0.05moles
H2SO4 ----------- SO4²- + 2H+
1moles ------- 6.02×10²³
2×0.05 moles -------- 6.02×10²³×0.1
=6.02×10²².

A is the correct answer.

Mass of hydrogen =2/98*4.9=0.1g

2g of hydrogen =6.02*10^23

0.1g=0.1*6.02*10^23/2=3.01*10^22
