What amount of conc. H ₂ SO ₄ solution should be used to prepare 500 ~mL of 0.5 M H ₂ SO ₄ ? (The concentration of H ₂ SO ₄ solution being used is 90 % and molecular mass of H ₂ SO ₄=98.079 ~g ~mol ⁻¹ )

Step-by-step solution

aligned & (d) M= mass ( m ) molar mass volume ( L ) & Given, M=0.5 M & Molar mass =98.079 & aligned V & =500 ~mL =0.5 ~L 0.5 & = m 98.079 0.5 m=24.52 ~g aligned aligned Concentration of H ₂ SO ₄=90 % Mass of solution required =27.24 ~g .
