<u>Answer:</u>
<u>For Part A:</u> The partial pressure of Helium is 218 mmHg.
<u>For Part B:</u> The mass of helium gas is 0.504 g.
<u>Explanation:</u>
- <u>For Part A:</u>
We are given:
To calculate the partial pressure of helium, we use the formula:
Putting values in above equation, we get:
Hence, the partial pressure of Helium is 218 mmHg.
- <u>For Part B:</u>
To calculate the mass of helium gas, we use the equation given by ideal gas:
PV = nRT
or,
where,
P = Pressure of helium gas = 218 mmHg
V = Volume of the helium gas = 10.2 L
m = Mass of helium gas = ? g
M = Molar mass of helium gas = 4 g/mol
R = Gas constant =
T = Temperature of helium gas = 283 K
Putting values in above equation, we get:
Hence, the mass of helium gas is 0.504 g.
