Answer:

The solubility of helium is #5.6 × 10^(-4) "mol·L"^(-1)#.

Explanation:

Henry's Law is often written as

#C = kP#,

where #C# is the concentration of the gas in the solution, #P# is the partial pressure of the gas, and #k# is a proportionality constant.

For your problem,

#C = kP = 3.70 × 10^(-4) "mol·L"^(-1)color(red)(cancel(color(black)("atm"^(-1)))) × 1.5 color(red)(cancel(color(black)("atm"))) = 5.6 × 10^(-4) "mol·L"^(-1)#.
