What will be the molarity of a solution, which contains 5.85g of NaCl_

1.	What will be the molarity of a solution, which contains 5.85g of NaCl_((s))per 500 mL ?
Answer» 4 mol `L^(-1)` 20 mol `L^(-1)` 0.2 mol `L^(-1)` 2 mol `L^(-1)` Solution :Molarity (M) is obtained by following equation, Molarity `=("weight" xx 1000)/("molecular weight" xx "volume (mL)")` `=(5.85xx1000)/(58.5xx500) = 0.2 "mol "L^(-1)` Note : Molarity of solution depends UPON the temperature because volume of solution is CHANGE with temerature .
