Question

What volume of 95%H2SO4 by weight(d=1.85gm/ml)and what mass of water must be taken to prepare 100ml of 15% solution of H2SO4(d=1.10gm/ml)

Answer 1

hey clear this answer nicely frm ur teacher. initially u have to find the volumes of both h2so4 solutions using the density and % terms. Then find the molarities using the volumes u calculated. finally use this formula which i m sure u knw, M1V1=M2V2

(V2 is 100 ml, u r asked to find V1). mass of water u can calculate easilh
