To calculate the number of molecules in <span>6.00 moles of hydrogen sulfide, H2S, the equivalence factor used is Avogadro's number equal to (6.022 x 10^23 molecules/mole). The answer is 6</span>.00 moles of hydrogen sulfide * <span>(6.022 x 10^23 molecules/mole) equal to 3.61 x10^24 molecules.</span>
(60)/(60+5.05)=.922367 C 1-0.922367=0.07763259 H (0.922367)(78.12)=72.05534204 C (0.07763259)(78.12)=6.06 H 72.05534204/(12.01)=6 C 6.06/1.01=6 H Empirical= CH Molecular=C6H6
