At 20 °C, 720 g of sodium chloride could be dissolved in 2 L of water.

First, we will convert 2 L of water to grams using the following relationships:

  • The density of water is 1 kg/L.
  • 1 kg = 1000 g.

\(2 L \times \frac{1kg}{L} \times \frac{1000g}{1kg} = 2000g\)

At 20 °C, the solubility of sodium chloride is 36.0 g per 100 g water. The mass of sodium chloride that can be dissolved in 2000 g of water is:

\(2000gH_2O \times \frac{36.0gNaCl}{100gH_2O} = 720 g NaCl\)

At 20 °C, 720 g of sodium chloride could be dissolved in 2 L of water.
