Vedclass · Answer

(A) According to Dalton's Law,the partial pressure $P_i$ of a gas is proportional to its mole fraction $x_i$ $(P_i = x_i P_{total})$.Since $P_i = \frac{n_i RT}{V}$,for equal masses $W$ of $CO$ and $N_2$:$n_{CO} = \frac{W}{M_{CO}} = \frac{W}{28}$ and $n_{N_2} = \frac{W}{M_{N_2}} = \frac{W}{28}$.Since the molar masses of $CO$ $(12+16=28 \ g/mol)$ and $N_2$ $(14 	imes 2=28 \ g/mol)$ are equal,the number of moles $n$ is the same for both gases.Therefore,$\frac{P_{CO}}{P_{N_2}} = \frac{n_{CO}}{n_{N_2}} = \frac{W/28}{W/28} = 1$.Thus,$P_{CO} = P_{N_2}$.

If equal masses of $CO$ and $N_2$ are filled in a container,the relationship between their partial pressures will be ................
