molarity
A solution has volume 200ml and molarity 0.1.if it is diluted 5times then calculate the molarity of reasulying solution and the amount of water added to it.
Relative humidity is the ratio of the partial pressure of water in air to the partial pressure of water in air saturated with water at the same temperature, stated as a percentage: Relative = Q : Analytical chemistry 37% weight of HCl 37% weight of HCl and density is 1.1g/ml. find molarity of HCl
37% weight of HCl and density is 1.1g/ml. find molarity of HCl
