37% weight of HCl and density is 1.1g/ml. find molarity of HCl
what is the molarity of the solution prepared by dissolving 75.5 g of pure KOH in 540 ml of solution
Determine the correct regarding Henry’s law: (1) The gas is in contact with the liquid must behave as an ideal gas (2) There must not be any chemical interaction among the gas and liquid (3) The pressure applied must be high (4) All of these.
