A $1\mathrm{.}22m$ aqueous solution of an ionic compound

with the formula $M{x}_2$ has a boiling point of $101\mathrm{.}66$

Calculate the van't Hoff factor $(i)$ for $M{x}_2$ at this concentrati

$C.$ The $K_b$ for water is $0\mathrm{.}512\frac{C}{m}.$

Express your answer using three significant figures.Use Henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas

that should bubble out of $1\mathrm{.}0L$ of water upon warming from $25C$ to $50C.$ Assume that the water is

initially saturated with nitrogen and oxygen gas at $25C$ and a total pressure of $1\mathrm{.}0$atm. Assume that the

gas bubbles out at a temperature of $50C.$ The solubility of oxygen gas at $50C$ is $27\mathrm{.}8m\frac{g}{L}$ at an

oxygen pressure of $1\mathrm{.}00$atm. The solubility of nitrogen gas at $50C$ is $14\mathrm{.}6m\frac{g}{L}$ at a nitrogen pressure

of $1\mathrm{.}00$atm. Assume that the air above the water contains an oxygen partial pressure of $0\mathrm{.}21$atm and a

nitrogen partial pressure of $0\mathrm{.}78$atm.

Express your answer using two significant figures.
