Question

If 300 mL of  M/20 H2SO4 (aq) solution is diluted to 3 litre. Calculated the molarity after dilution.​

Answer 1

Answer:

Let M1(molarity H2SO4)=2M, V1(volume of H2SO4)=20ml=0.02L, V2(volume of solution)=1L and M2(molarity of resulting solution)=?

Therefore, M1×V1=M2×V2

M2=0.04M

Normality=M2×n , here n is number of H+ ions an acid can donate

Normality=0.04×2=0.08N
