Abubble of helium gas has a volume of 0.650 cm3 near the bottom of a large aquarium where the pressure is 1.54 atm and the temperature is 12°c. determine the bubble’s volume upon rising near the top where the pressure is 1.01 atm and 16°c. assume that the number of moles of helium remains constant and that the helium is an ideal gas. (13 pts)
important equations and constants 1 atm = 760 torr = 760 mmhg = 101,325 pa
1ml = 1cm3
pv = nrt
p1v1 = p2v2
v1/t1 = v2/t2
v1/n1 = v2/n2
ptotal = p1 + p2 + p3 + ….
(p1v1)/(n1t1) = (p2v2)/(n2t2)
r = 0.08206 l atm/mol k
