40% by weight solution will contain how much mass of the solute in 1 solution, density of the solution is 1.2 g/mLA. 480 gB. 48 gC. 38 gD. 380 g |

Answer» Correct Answer - A Molarity `= ("% by weight of solute" xx "density of solution" xx 10"(in litre)")/(M)` when M = mol. Weight of the solute Molarity `=(40xx1.2xx10)/(Mxx1000)` .......(i) Molarity `=("weight of the solute / M")/("volume of solution (in litre)")`. .........(ii) From Eqs. (i) and (ii) `("Weight of solute")/(M xx 1000)=(40xx1.2xx10)/(M xx 1000)` Weight of solute = 480 g. |
