    [NaCl] = 0.45 M

    Explanation:

    First of all, you should be sure of what sort of concentration do you need. There are many ways to express concentration in a solution.

    Let's calculate molarity. This is moles of solute in 1 L of solution.

    Molar mass NaCl = 58.45 g/m

    Mass / Molar mass = Mol → 9.3 g / 58.45 g/m = 0.159 moles

    Volume of solution is 350 mL

    Convert mL to L (/1000)

    350 mL / 1000 = 0.350L

    0.159 moles / 0.350L = 0.45 M
