For this problem, we’re being asked to rank the compounds from the least to the greatest number of hydrogen atoms contained in the samples.
The flow for this problem will be like this:
Mass compound (molar mass compound) → Moles of compound (mole-to-mole comparison) → Moles of H (Avogadro’s number) → Atoms H
Consider samples of phosphine (PH3), water (H2O), hydrogen sulfide (H2S), and hydrogen fluoride (HF), each with a mass of 119 g. Rank the compounds from the least to the greatest number of hydrogen atoms contained in the samples.
