What Is The Empirical Formula Of Phosphorus Selenide. Atomic mass of selenium = 79g. The molecular formula shows the composition of the molecules.
Web what is the empirical formula of the phosphorus selenide? 45.2/31 = 1.45 which is nearly 1.5 mol of p. The formula for phosphorus trichloride is pcl3. A 1.45 − g sample of phosphorus. Ag2o a compound containing phosphorus and oxygen has a molar mass of 219.9. Web carbon = 79.9g hydrogen = 20.1g (work out the mass of each element) 79.9/12 = 6.66 20.1/1 = 20.1 (divide mass by atomic mass number) ratio = 6.66 :… 1 = 1:3 (simplify to find. Web tants | periodic table part a a 43.6 mg sample of phosphorus reacts with selenium to form 127 mg of the compound. Applying the law of conservation of mass: Atomic mass of phosphorous = 31g. Find the moles of each and compare to get the ratio of atoms.
Atomic mass of phosphorous = 31g. Ag2o a compound containing phosphorus and oxygen has a molar mass of 219.9. Web so the empirical formula for phosphorus selenide is p3se2. What is the formula for phosphorus trichloride? Web an empirical formula is one that shows the lowest whole number ratio of the elements present. Web tants | periodic table part a a 43.6 mg sample of phosphorus reacts with selenium to form 127 mg of the compound. Web what is the empirical formula of the phosphorus selenide? Web carbon = 79.9g hydrogen = 20.1g (work out the mass of each element) 79.9/12 = 6.66 20.1/1 = 20.1 (divide mass by atomic mass number) ratio = 6.66 :… 1 = 1:3 (simplify to find. Atomic mass of phosphorous = 31g. The formula for phosphorus trichloride is pcl3. What are the differences between empirical and molecular formulas?
