Question

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

Answer 1

Almost 100 g of sodium nitrate can be dissolved at this temperature.

Explanation:

This site lists the solubility of `NaNO_3` in water at `30` `""^@C` as `94.9*g` per `100*mL`. Given that the volume of the solution would change only marginally, can you convert this into a quantity in `mol*L^-1`?
