Question

An 8.5 l tire is filled with 0.55 moles of gas at a temperature of 305 k. what is the pressure of the gas in the tire?

Answer 1

the question asks for to answer to 2 significant figures, therefore the true answer is 1.6

Step-by-step explanation:

Answer 2

As per the gas equation:

P = ( n ) ( R ) ( T ) / ( V )

n = number of moles

R = Gas Constant = 0.08206 atm - L / gmol - K

T = Temperature in Kelvin

V= Volume in meters

P = ( n ) ( R ) ( T ) / ( V )

P = {0.55 gmol x 0.08206 atm - L / gmol - K x 305 K }/ 8.5 L

P = 1.62 atm
