1. To increase the solubility of a gas at constant temperature from 0.85g/mL at 1.0atm to 5.1g/mL, the pressure would have to be increased to . *

Answer : The pressure would have to be increased to 6.0 atm.

Explanation :

According top the Henry's Law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas.

or,

where,

= initial solubility of gas = 0.85 g/mL

= final solubility of gas = 5.1 g/mL

= initial pressure of gas = 1.0 atm

= final pressure of gas = ?

Now put all the given values in the above formula, we get the final pressure of the gas.

Therefore, the pressure would have to be increased to 6.0 atm.
