Question
You're holding two balloons, each of which is filled with the same mass of gas. One balloon contains hydrogen gas (H2) the other balloon contains helium gas (He). Which of the following statements is correct?(A). The balloon filled with hydrogen is twice as large as the balloon filled with helium.
(B). The balloon filled with helium is twice as large as the balloon filled with hydrogen
(C). The balloons have equal volumes You're holding two balloons, each of which is filled with the same mass of gas. One balloon contains hydrogen gas (H2) the other balloon contains helium gas (He). Which of the following statements is correct?
(A). The balloon filled with hydrogen is twice as large as the balloon filled with helium.

(C). The balloons have equal volumes
(A). The balloon filled with hydrogen is twice as large as the balloon filled with helium.
(B). The balloon filled with helium is twice as large as the balloon filled with hydrogen
(C). The balloons have equal volumes
Explanation / Answer
We apply PV = nRT
As we assume T,P are constant
Volume of the balloons will be dependent only on the moles of the gases
Therefore we know the mass of gases are equal . Let suppose the mass is x gms
moles of H2 = x/2
moles of He = x/4
Volume of H2 / Volume of He = 2
Therefore volume of H2 will be = 2* volume of He
(A). The balloon filled with hydrogen is twice as large as the balloon filled with helium.
