Question #2f78d

Answer 1

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)`.
