Determine the molarity of a solution formed by dissolving 97.7 g libr in enough water to yield 750.0 ml of solution.

a) 1.50 m
b) 1.18 m
c) 0.130 m
d) 0.768 m
e) 2.30 m

A. 1.50 M

Explanation:

Concentration is the number of moles of solute dissolved in a volume of 1 L of solution

Mass of LiBr - 97.7 g

Number of moles of LiBr - 97.7 g /87 g/mol = 1.12 mol

Equation for concentration is as follows

Concentration = number of moles / volume of solution in L

Substituting the values

Concentration = 1.12 mol / 0.7500 L

Concentration of LiBr is 1.50 mol/L
