0.02M H2SO4 contains 0.02mol H2SO4 in 1.0L =1000mL(since 1M =1mol/litre) solution
100mL solution will contain 0.02*100/1000 = 0.002 mol H2SO4
1 mol H2SO4 contains 6.022*10^23 molecules
0.002 mol H2SO4 contains 0.002*6.022*10^23 = 1.20*10^21 molecules.
100mL solution will contain 0.02*100/1000 = 0.002 mol H2SO4
1 mol H2SO4 contains 6.022*10^23 molecules
0.002 mol H2SO4 contains 0.002*6.022*10^23 = 1.20*10^21 molecules.
