Web8 okt. 2024 · CBSE Class 11-science Answered 1 gram mixture of cuprous and cupric oxides was reduced to 0.839 gram metallic copper. What is the weight of cuprous oxide in sample Asked by shahrithik07 08 Oct, 2024, 09:25: AM Expert Answer The reaction equations are: weight of Cu 2 O is 0.45 g Answered by Varsha 08 Oct, 2024, 11:30: … WebThe atomic weight of a single oxygen atom is roughly 16.00 g/mol. So, the molecular weight of the oxide is : (2 × at. wt. M) + (3 × at. wt. O) or, (2 × at. wt. M) + 48.00 g/mol But the oxide is 68% metal, so 2 × at. wt. M / (2 × at. wt. M) + (48.00 g/mol) = 0.68 Simplifying, with ‘M' standing for the atomic weight of the unknown metal,

WebIf the weight of metal oxide is xg containing y g of oxygen, the equivalent weight of metal will be 8x (1) E (2) E = 8 (y - x) y (4) E-81- y) Solution Verified by Toppr Was this answer … Web29 jul. 2014 · You calculate the molar ratios of each element in the oxide. EXAMPLE. When a 2.50 g sample of copper is heated, it forms 3.13 g of an oxide. What is its empirical formula. Solution. Step 1. Determine the masses. Mass of Cu = 2.50 g. Mass of O = (3.13 – 2.50) g = 0.63 g. Step 2. Determine the moles the vision ministry
