You are holding two balloons of the same volume. One balloon contains 1.05 g helium. The other balloon contains neon. What is the mass of neon in the balloon?

Question

Quizplus · Accepted Answer

The mass of neon can be calculated using the molar mass ratio. Helium has a molar mass of 4 g/mol, and neon has a molar mass of 20 g/mol. Since the balloons have the same volume, they contain the same number of moles. Therefore, the mass of neon is (20/4) times the mass of helium, which is 5.29 g.
