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).
