Times 100 and for oxygen, it'll be grams of oxygen divided by the grams of the compound. For example, water has 3 atoms, one hydrogen and two oxygens. E) the weight of a sample of the substance. Nitrogen: 30.4 / 14 = 2.1714 Oxygen: 69.6 / 16 = 4.35 compare these and divide by the smallest, round if necessary. What is the molecular weight of nitric oxide? NOTE: Even though mass has units, mass percent is unit-less, and so care needs to be taken to identify what the percent or fraction relates to. Oxygen has a molar mass of 15.9994 g/mol and nitrogen has a molar mass of 14.0067 g/mol. Oxygen: O: 15.9994: 2: 69.554%: . What is the formula for mass percent of solvent? So you have 1 times the mass of nitrogen plus 2 times the mass of oxygen. 7H2O. If computing the moles of NO2, NO, and/or HONO from NEI NOx data and speciation factors, we recommend that one should therefore use the molecular weight of NO2. This gives an empirical formula of NO2 D. CH_3CH_2CH_3. what would be the percent H in a 20.000 g sample? section 9.2 1. The mass percentage of the Nitrogen = (14/30) 100 = 46.67 %. 13 Points. First, calculate the molar mass of the compound and then the percentage of each element by dividing the total mass of the element present in the compound by the molecular mass of the compound multiplied by 100. >.
