A cylinder with a movable piston contains 2.00 g of helium, He, at room temperature. More helium was added to the cylinder and the volume was adjusted so that the gas pressure remained the same. How many grams of helium were added to the cylinder if the volume was changed from 2.00 L to 4.10 L? (The temperature was held constant.)

0.358g

Explanation:

Density of Helium = 0.179g/L

ρ=m/v

m=ρv

when the volume was 2L

m1 = 0.179*2

m1=0.358g

when the volume increased to 4L

m2 = 0.179*4

m2=0.716g

gram of helium added = 0.716g-0.358g

=0.358g
