Marquis · Answer 1

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
