Q4 Describe which sample (A or B) has the greatest mass. show your work.
(Ai-Level 5-6)
Sample A has 6.0 x 1025 molecules of hydrogen (H2)
Sample B has 5.0 mol of neon atoms (Ne)
Atomic mass of H= 1.01 g/mol
Atomic mass of Ne = 20.18 g/mol

Equal numbers of moles of he(g), ar(g), and ne(g) are placed in a glass vessel at room temperature. if the vessel has a pinhole-sized leak, which of the following will be true regarding the relative values of the partial pressures of the gases remaining in the vessel after some of the gas mixture has effused?
