How many grams of NaNO_3 can dissolved in 100 grams of water at 30°C?

This site lists the solubility of $N a N {O}_{3}$ in water at $30$ ""^@C as $94.9 \cdot g$ per $100 \cdot m L$. Given that the volume of the solution would change only marginally, can you convert this into a quantity in $m o l \cdot {L}^{-} 1$?
