can somebody help me in solving these calculations. These are from apha book.
1- calculate the amount of water (in grams) in 100ml of 65%w/w syrup that has a density of 1.313.
2- how many milligrams of sodium chloride are required to make 30ml of a solution of 1% dibucaine Hcl isotonic with tears.
freezing point depression of 1% dibucaine Hcl solution is -0.08 C and the freezing point depression of an isotonic solution is -0.52C.
Kindly calculate stepwise to understand easily. thanks
