Answer: The mass of chlorine gas is 4.54 grams.
Explanation:
To calculate the mass of the gas, we use the equation given by ideal gas equation:
[tex]PV=nRT[/tex]
Or,
[tex]PV=\frac{m}{M}RT[/tex]
where,
P = pressure of the gas = 98.7 kPa
V = Volume of gas = 3.34 L
m = given mass of chlorine gas = ?
M = Molar mass of chlorine gas = 35.45 g/mol
R = Gas constant = [tex]8.31\text{ L kPa }mol^{-1}K^{-1}[/tex]
T = Temperature of the gas = [tex]37^oC=[37+273]=310K[/tex]
Putting values in above equation, we get:
[tex]98.7kPa\times 3.34L=\frac{m}{35.45g/mol}\times 8.31\text{ L kPa }mol^{-1}K^{-1}\times 310K\\\\m=4.54g[/tex]
Hence, the mass of chlorine gas is 4.54 grams.
