# How many grams of NaCl are contained in 350. mL of a 0.287 M olution of sodium chloride?

Dec 12, 2016

Approx. $6 \cdot g$ of salt.

#### Explanation:

$\text{Concentration}$ $=$ $\text{Moles of solute"/"Volume of solution}$

And thus, $\text{moles of solute"="concentration"xx"volume of solution}$.

So, $\text{moles}$ $=$ $350 \times {10}^{-} 3 \cdot L \times 0.287 \cdot m o l \cdot {L}^{-} 1 = 0.100 \cdot m o l$.

And $\text{mass of salt}$ $=$ 0.100*molxx58.44*g*mol=??g
