[Tutorial: Empirical formula) This question will walk you through the process of calculating the empirical formula of a 100.0 g sample of an unknown compound from its elemental percent compositions. This problem will be solved via the following sequence of conversions: mass % mass → moles mole ratio → empirical formula. a) Step 1a: When percentages are given, assume that the total mass is 100 grams to determine the mass of each element in grams. (mass % = mass). Then, using the molar masses of each

[Tutorial: Empirical formula) This question will walk you through the process of calculating the empirical formula of a 100.0 g sample of an unknown compound from its elemental percent compositions. This problem will be solved via the following sequence of conversions: mass % mass → moles mole ratio → empirical formula.
a) Step 1a: When percentages are given, assume that the total mass is 100 grams to determine the mass of each element in grams. (mass % = mass). Then, using the molar masses of each element, convert grams to moles (mass → moles). The unknown compound is 66.6% N by mass. What quantity in moles of nitrogen does a 100.0 gram sample of the unknown compound contain?
b) The unknown compound is 28.6% C by mass. What quantity in moles of carbon does a 100.0 gram sample of the unknown compound contain?
c) The unknown compound is 4.8% H by mass. What quantity in moles of hydrogen does a 100.0 gram sample of the unknown compound contain
