Question

A gas cylinder contains 2.0 mol of gas X and 6.0 mol of gas Y at a total pressure of 2.1 atm. What is the partial pressure of gas Y? Use mc017-1.jpg. 0.50 atm 1.6 atm 2.1 atm 2.8 atm

Answer 1

B) 1.6 ATM is the answer hope this helps anyone who needs this answer.

Answer 2

The partial pressure of gas Y is 1.6 atm

calculation

• Total pressure = partial pressure of gas y + partial pressure of gas X

• partial pressure of gas Y = moles of gas Y/total moles x total mole

moles of of gas y= 6.0 moles

total moles = 6.0 + 2.0 = 8 moles

total pressure = 2.1 atm

• partial pressure of gas y is therefore
• = 6.0 mole /8.0 mole x 2.1 atm= 1.6 atm
