<u>Answer:</u> The mass of chlorine gas is 4.54 grams.
<u>Explanation:</u>
To calculate the mass of the gas, we use the equation given by ideal gas equation:
Or,
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 =
T = Temperature of the gas =
Putting values in above equation, we get:
Hence, the mass of chlorine gas is 4.54 grams.
