Answer:
[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
