Web15 okt. 2024 · Ans. The amount of matter contained in an atom of an element is called its atomic mass. It is given as a multiple of one-twelfth the mass of the carbon-12 atom, … WebThis problem provides the mass in grams of each element. Begin by finding the moles of each: 34.97 g Fe ( mol Fe 55.85 g) = 0.6261 mol Fe 15.03 g O ( mol O 16.00 g) = 0.9394 mol O Next, derive the iron-to-oxygen molar ratio by dividing by the lesser number of moles: 0.6261 0.6261 = 1.000 mol Fe 0.9394 0.6261 = 1.500 mol O
How does stoichiometry support the law of conservation of mass?
Web8 apr. 2024 · I will theoretically calculate the mass of the reactants and products. Reactants H 2 = 1 x2 = 2 g Cl 2 = 35.5 X 2= 71 g Total = 73 grams Products 36.5 x2 = 73 grams So theoretically we have same mass of reactants and products. Example 2 Verify that this equation supports law of conservation of matter Mg + 2HCl == MgCl 2 + H 2 Solution For … WebBorax (also referred to as sodium borate, tincal / ˈ t ɪ ŋ k əl / and tincar / ˈ t ɪ ŋ k ər /) is a salt (ionic compound), a hydrated or anhydrous borate of sodium, with the chemical formula Na 2 H 20 B 4 O 17.
