Answer:
The square root of the molar mass of B ÷ the square root of the molar mass of A
Explanation:
Graham’s Law applies to the effusion of gases:
The rate of effusion (r) of a gas is inversely proportional to the square root of its molar mass (M).
If you have two gases A and B, the ratio of their rates of effusion is
The temperature : 332.75 K
<h3>Further explanation</h3>Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
volume of gas = 790 cm³ = 0.79 L
mol of gas at STP :
Use ideal gas :
P=726 mmHg=0.955 atm
V= 1000 cm³ = 1 L
