Answer:
Approximately 192 gram of sodium nitrate
Explanation:
First we shall look at the solubility curves of NaNO3.
Now, the solubility graph will allow you to find the solubility of the solute per 100 g of water at various temperatures.
At 30∘C, Sodium Nitrate has a solubility of approximately 96 g per 100 g of water.
We will use this value as a conversion factor to determine how much Sodium Nitrate can be dissolved in 200 g of water at 30∘C.
200 gram of water *(96 gram of NaNO3 at 30 degree centigrade)/(100 gram of water)=192 gram of NaNO3
