Question

One mole of any substance contains `6.022xx10^(23)` atoms/molecules. Number of molecules of `H_(2)SO_(4)` present in 100mL of 0.02M `H_2SO_(4)` solution is
A. `12.044 xx 10^(20)` molecules
B. `6.022 xx 10^(23)` molecules
C. `1 xx 10^(23)` molecules
D. `12.044 xx 10^(23)` molecules

Answer 1

Correct Answer - A
no of moles `(n) = M xx V` (Litres)
no of molecule `= n xx N_(A)`
