Molar concentration also known as molarity and can be denoted by the unit m molar. Hcl consists of one hydrogen atom atomic weight 1 g mole and one chlorine atom atomic weight 35 g mole so its molecular weight is 36 g mole.
Next calculate the mass volume percent solution.
Molarity from mass percent. 1 mass percent or 2 molality or 3 mole fraction and no density you could not get the molarity or the density. Another unit of the concentration weight percentage refers to the ratio of the mass of the solute a dissolved substance to the mass of the solution. Molarity is the number of moles of a substance in 1 liter of the solution.
The answer is 5 7 moles liter. The basic formula for mass percent of a compound is. Note that the convention in molarity is to divide moles by liters but the convention in mass percent is to divide grams by milliliters.
However suppose you are given one of these. If you were only given two of these. If you prefer to think only in terms of liters not milliliters then simply consider mass percent as kilograms divided by liters.
Converting between concentrations is frequently required for various problems in chemistry. The molar mass of a compound is the amount of mass for one mole of an element while the molecular mass is the amount of mass for one mole of the entire compound. Divide this into the weight in the solution to get 0 51 moles.
Mass percent molar mass of element total molecular mass of compound x 100. 1 mass percent or 2 molality or 3 mole fraction and then also given molarity instead of the density. To prepare 1 l of 0 5 m sodium chloride solution then as per the formula use 29 22 g of sodium chloride 0 5 mol l 1l 58 44 g mol 29 22 g.
Its units are mol l mol dm 3 or mol m 3. To find molarity divide this number by the volume which is 0 09 liters.
