Question #$8$

The Henry's law constant for $O_2$ is $1\mathrm{.}3{10}^{-3}\frac{M}{a}tm$ at $25C.$ What is the concentration of dissolved oxygen gas in water at $25C$ when the atmospheric pressure is $0\mathrm{.}91$ atm?

$[O_2]=$

M

What mass of oxygen would be dissolved in a $36L$ aquarium under these conditions? $($Note: Oxygen is $21\%$ of air.$)$ mass $=$ ;$O_2$

$$ Points: $0\mathrm{.}00$ out of $2$

Incorrect.

$C_{O_2}=k_{O_2}{P}_{O_2}$ with $P_{O_2}=21\%of{P}_{\text{a}\text{i}\text{r}}$

Incorrect. Use the given aquarium volume, the concentration determined in part one, and the appropriate conversion factor to calculate the mass of $O_2.$
