Answer :
The number of moles of helium occupying a volume of 5.00 L at 227.0°C and 5.00 atm is approximately 0.609 mol. Hence, the correct option is: c)
How can we calculate the number of moles of helium?
To calculate the number of moles, we can use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.
To determine the number of moles, we can use the ideal gas law equation:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.
Given:
P = 5.00 atm
V = 5.00 L
T = 227.0°C = (227.0 + 273) K = 500 K (converting to Kelvin)
Now, we can rearrange the ideal gas law equation to solve for the number of moles:
n = (PV) / (RT)
Substituting the given values into the equation:
n = (5.00 atm * 5.00 L) / (0.0821 atm·L/(mol·K) * 500 K)
Calculating this expression gives the number of moles, which is approximately 0.609 mol.
Therefore, the correct option is c) 0.609 mol.
