WebFeb 17, 2024 · Step 1: Mass percent = (mass of chemical / total mass of compound) x 100 is used as the formula to determine mass percent of a compound. In order to express the value as a percentage, we must multiply 100 at the top. Step 2: The second step is to find the compound’s total mass. WebJan 27, 2024 · 1st Step: Calculate the mass of each element in grams. Element percentage \ ( = \) mass in grams \ ( = {\text {m}}\) 2nd Step: Count the number of moles of each type of atom that is present. \ ( {\rm {m/atomic mass}}\, {\rm … WebSo what the percentage is depends on what kind of percent you're talking about. HgCl₂ has one atom of Hg per 2 atoms of Cl. Thus by moles it is ⅓ Hg and ⅔ Cl. By mass, since Hg is heavier the percentages are: Hg: 1 mol × 200.59 g/mol = 200.59 g Cl: 2 mol × 35.45 g/mol = 70.90 g HgCl₂: 1 mol × 271.49 g/mol = 271.49 g Thus, by mass: methane atomic orbit structure
