Na : atomic mass = 23
Cl : atomic mass = 35
atomic mass of compound = 58 g/mole
350. mL = 0.35 L
.376 Molar solution means 58 moles / liter
(58 * (grams / mole)) * (.376 * (moles / liter)) * (.35 L) = 7.6328 grams

Use this formula
g = Mc x VL x Fw
grams equal molar concentration x volume in liters x molar mass (formula weight)
g = 0.376mol/L x 0.350L x 58.4 g/mol

Molarity = moles of solute /liters of solution
M=n/V
n=M*V
moles=.376M*.350L
=0.132 moles of NaCl in solution
0.132 moles NaCl*molar mass NaCl (58.45)
7.69 grams of NaCl!!
Try it yourself and round to appropriate sig figs.
