Question 3.a of 5 [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. 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. How many moles of nitrogen does a 100.0 gram sample of the unknown compound contain? mol 7 8 9. +/- x 100 MacBook Air 2. 5 1, 4.

Individual atoms, ions, molecules are small and light that can't be measured with normal balances. Avogadro's number, 6.022 x 1023, is used to scale them up. A collection of 6.022 x 10 23 particles is defined as one mole. Mass of one mole of a substance is called molar mass, with a unit g/mol. Mass of one mole of a substances usually weight in grams, which can be measured with a conventional balance. In 1794, Joseph Proust published the Law of Definite Proportions, for which he is most famous for. Proust stated this law the following way: "A chemical compound always contains the same elements combined together in the same proportion by mass." This law implies that a known substance has a known composition, thus a known chemical formula. Based on the chemical formula, we can calculate the molar mass of the substances by summing up each atom's atomic weight. Avogadro's number and molar mass are the two most fundamental mole concepts. They are used to connect the number of particles on…
