Answer #1

partial pressure of A PA =0.417 atm

partial pressure of B PB =0.773 atm

volume V =8.05 L

temperature T=110C =273+11 =284 K

moles of gas C =0,110moles

since there is no change in volume or temperature therefore we can assume the gas C to be ideal in nature and ideal gas equation can be used to calculate the pressure of Gas C

PV=nRT

Pc = nRT/V

Pc = 0.110 moles *0.0826 atm L K-1 mol-1 *284 k/ 8.05l

Pc = 2.580 atm /8.05

Pc =0.32 atm

according to Dalton's Law of Partial Pressures.: in a gaseous mixture, the partial pressure of a gaseous component is the same as the pressure it would exert if it alone occupied the container.

Ptotal =PA+PB+PC

Ptotal = 0.417 atm +0.773 atm +0.32 atm

Ptotal =1.51 atm
