Answer :
Final answer:
The mass of NaCl that can be dissolved in 50.0 g of H₂O is 18.1 g.
Explanation:
To find the mass of NaCl that can be dissolved in 50.0 g of H₂O, we need to use the given solubility value. The solubility of NaCl at 25 °C is 36.2 g/100 g H₂O. This means that 100 g of water can dissolve 36.2 g of NaCl.
Since we have 50.0 g of H₂O, we can set up a proportion:
36.2 g NaCl / 100 g H₂O = x g NaCl / 50.0 g H₂O
Cross-multiplying, we get:
x = (36.2 g NaCl / 100 g H₂O) * 50.0 g H₂O = 18.1 g NaCl
Therefore, the mass of NaCl that can be dissolved in 50.0 g of H₂O is 18.1 g.
