Answer:
1.77 atm
Explanation:
Total pressure in a mixture is, the sum of partial pressures from each gas.
Let's analyse with the Universal Gases Law
Total pressure . V = (total moles) . R . T
Partial pressure of a gas . V = (mol of that gas) . R . T
Mole fraction:
Partial pressure of a gas / Total pressure = moles of the gas / Total moles
Then, total pressure in this mixture is:
1.45 atm + 0.32 atm = 1.77 atm
