WebFeb 10, 2024 · To know the number of atoms, it will be necessary to use the formula of avogadro. We calculate the number of moles then we can calculate the number of avogadro. The molar mass of: Phosphorus = 31g / mol. Mercury = 200 g / mol. Bismuth = 209 g / mol. Strontium = 87 g / mol. The number of avogadro (N) is 6.023 10 ^ 23. n = m (mass) / M … WebAug 30, 2024 · As a general rule, in the case of the representative elements, the distinguishing electron will be in an ns or np subshell. The value of n, the principal quantum number for the distinguishing electron, can be quickly determined by counting down from the top of the periodic table. For example, iodine is a representative element in the fifth …

WebQuestion: Calculate the number of atoms in a 5.08 x 10 g sample of silicon. atoms This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. WebThe molar mass of sodium chloride is 58.44 g/mol, which is the sum of the atomic masses of 1 mole of sodium (Na, 22.99 g/mol) and 1 mole of chlorine (Cl, 35.45 g/mol). Two moles of table salt, NaCl, would be twice this amount: m = 2 × 58.44 m = 116.88 g So, the mass of 2 moles of sodium chloride is 116.88 grams. cylindrical hand warmers
