2.The solubility of sodium chloride at 20 degrees Celsius is 358g/1000g H20, or 358g/1358g solution. How many grams of sodium chloride would you expect to dissolve in 2200 grams of H20 at 20 degrees Celsius?

358 x (2200/1000) = ?

787.6 To calculate the grams of sodium chloride that would dissolve in 2200 grams of water at 20 degrees Celsius, we can use the information given about the solubility of sodium chloride.

The solubility of sodium chloride at 20 degrees Celsius is 358g/1000g H2O. This means that 358 grams of sodium chloride can dissolve in 1000 grams of water at this temperature.

To find out how much sodium chloride would dissolve in 2200 grams of water, we can set up a proportion:

(358 grams sodium chloride) / (1000 grams water) = (x grams sodium chloride) / (2200 grams water)

Cross-multiplying this proportion gives us:

(358 grams sodium chloride) * (2200 grams water) = (1000 grams water) * (x grams sodium chloride)

Simplifying further:

x grams sodium chloride = (358 grams sodium chloride) * (2200 grams water) / (1000 grams water)

Now we can calculate the value of x:

x = (358 * 2200) / 1000

x ≈ 787.6 grams

Therefore, we would expect approximately 787.6 grams of sodium chloride to dissolve in 2200 grams of water at 20 degrees Celsius.
