1.560 x 10-4 mol of an unidentified gaseous substance effuses through a tiny hole in 98.8 s.
Under identical conditions, 1.749 x 10-4 mol of argon gas takes 84.9 s to effuse.
What is the molar mass of the unidentified substance (in g/mol)?
The percentage C by mass in the above unidentified substance is 53.0%. It may also contain H and/or O, but no other element.
What is the molecular formula of the substance?
In typing this formula use the convention of C first, H second and O last. For example, C6H8O2 would be C6H802.)
Under identical conditions, how many moles of acetylene (C2H2) gas would effuse in 86.5 s?
