Answer:
271.0 L
Explanation:
Given data:
Number of moles of hydrogen = 12.1 mol
Volume = ?
Solution:
The one mole of gas at standard temperature and pressure occupy the volume of 22.4 L.
One mole volume = 22.4 L
For 12.1 mol,
12.1 mol × 22.4 L / 1 mol
271.0 L
Now by putting the standard conditions we can calculate the number of moles and check the answer weather it is wrong or right.
Formula:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
standard temperature = 273.15 K
standard pressure = 1 atm
Now we will put the values in formula.
PV = nRT
n = 1 atm × 271.0 L / 0.0821 atm.L/mol.K × 273.15 K
n = 271.0 L .atm / 22.4 atm. L/mol
n = 12.1 mol
so answer is correct
