Question

Calculate the molarity of 30ml of0.5m h2so4 diluted to 500ml

Answer 1

hello mate

Volume of H2SO4 (V1) = 30 ml)

Diluted volume of H2SO4 (V2) = 500 ml

Number of moles present in 1000 mL of 0.5 M H2SO4 = 0.5 mol

Initial molarity M1= 0.5 M 

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

M2V2 = M1V1

M2  × 500  = 0.5 × 30

M2 = 15/ 500 = 0.03 M
