Answer to Question #66277 in General Chemistry for Chris
Question #66277
Exercise 5.10
A cylinder with a moveable piston contains 0.91 mol of gas and has a volume of 315 mL .
What is its volume after an additional 0.16 mol of gas is added to the cylinder? (Assume constant temperature and pressure.)
Express your answer to three significant figures.

Expert's answer
Answer:
pV=nRT
p·0.000315=0.91·RT
In order the balance to be maintained, equal correlation must be in place. In this case correlation between the figures is: 0.91/0.000315 = 2888.889
n1 = 0.91+0.16 = 1.07 mol
p ·X = 1.07 ·RT
х = 1.07/2888.889 = 0.000370 m3 = 370 ml
