One point earned for determination of molarity One point earned for conversion of molarity to molar mass . OR, moles solute = ( T x kg solvent) / Kf = 0.00611 mol (one point) molar mass = 1.570 g / 0.00611 mol = 257 g / mol (one point) OR, molar mass = (mass x Kf) / ( T x kg solvent) = 257 g / mol …
Molarity - Quia
The molarity of a solution is often used as a conversion factor between moles of solute and volume of solution: it is a “molar density”. Interpreting molar solutions: A 1.0 …

molarity (mol/dm3) = mol / volume (dm3=cm3/1000), In most volumetric calculations of this type, you first calculate the known moles of one reactant from a volume and molarity. Then, from the equation, you relate this to the number of moles of the other reactant, and then with the volume of the unknown concentration, you work out its molarity.

Use them to solve the next few problems, or use standard conversion techniques: Example. of # moles = M x L: How many moles are in 250. mL of 2.0 M CaCl2? How many grams is this? Begin with the value you are given in the problem (250. mL), then use molarity of CaCl. 2 (2.0 M) as a conversion factor.250. mL (1 L) (2.0 mol CaCl. 2) = 0.50 mol ...
