1.	In a solution of commion salt is wates ther ofsal to water was s0-as per weight. If we evaporatthis solution, what will be the ratio of the salt to water by weight?7.
Answer» Salt:water = 30:70so in ikg solution salt=300g and water =700g.now 100g water is evaporated so net water =600g so the ratio would be 300:600=1:2.now for 100g the ratio would be (100/3):(200/3) i.e. approximately 33.33:66.67
