Question

calculate the molarity of a solution containing 30ml of 0.5M H2SO4 diluted to 500ml.

Answer 1

volume of H2SO4 (V1) = 30ml

diluted volume of H2SO4  (V2)= 500ml

no of moles present in 1000ml of 0.5 M H2SO4= 0.5 Mol

initial molarity M1= 0.5 M

we have to find M2(molarity of 500ml of solution )

M2V2 =M1V1

M2*500= 0.5*30

M2=15/500=0.03M
