A) 59 M/atm
B) 0.017 M/atm
C) 0.029 M/atm
D) 35 M/atm
E) 0.038 M/atm

Quizplus · Accepted Answer

Henry's law states that the solubility of a gas in a liquid at a given temperature is directly proportional to the pressure of the gas above the liquid. The formula for Henry's law is given by $C = kP$, where $C$ is the concentration of the gas in the liquid, $k$ is Henry's law constant, and $P$ is the partial pressure of the gas. Rearranging the formula to solve for $k$, we get $k = \frac{C}{P}$. Substituting the given values, $k = \frac{1.3}{0.022} = 59$ M/atm.
