    molarity: 2.4 M

    Explanation:

    1. Suppose you have 100 mL de solution:

    Use density to find grams of soluton:

    100 mL solution x (1.10 g / 1 mL) = 110 g solution

    2. FInd the amount of sodium chloride pure:

    110 g solution x (13 g NaCl / 100 g solution) = 14.3 g NaCl

    3. Change grams to mol:

    14.3 g NaCl x (1 mol NaCl / 58.44 g NaCl) = 0.24 mol NaCl

    4. Molarity:

    M = mol NaCl / L solution

    M = 0.24 mol NaCl / 0.1 L = 2.4 M
