f the solubility of sodium chloride (NaCl) is 30.6 g/100 mL of H2O at a given temperature, how many grams of NaCl can be dissolved in 250.0 mL of H2O

Respuesta :

Answer:

76.5 grams

Explanation:

Solubility of sodium chloride = [tex]\dfrac{30.6}{100}=0.306\ \text{g/mL}[/tex]

Now volume of water is 250 mL

We have to find the amount of NaCl that can be dissolved in the above mentioned amount of water

Let the mass of NaCl that can be dissolved be m so

[tex]\dfrac{m}{250}=0.306\\\Rightarrow m=250\times0.306\\\Rightarrow m=76.5\ \text{g}[/tex]

The mass of NaCl that can be dissolved is 76.5 grams.
