The basic equation = mass of element / mass of compound X 100%. For instance, if you had a 80.0 g sample of a compound that was 20.0 g element X and 60.0 g element y then the percent composition of each element would be:

Web1 mol CuSO4= 159.62 g/mol 1 mol Cu = 63.55 g/mol. Since the amount of product in grams is not required, only the molar mass of the reactants is needed. Balance the equation. The chemical equation is already balanced. The balanced equation provides the relationship of 1 mol CuSO4 to 1 mol Zn to 1 mol Cu to 1 mol ZnSO4. google my google activity
Which metal heats up fastest, Aluminum, Copper, or Silver?
WebJul 29, 2014 · Step 2. Determine the moles. Moles of Cu = 2.50 g Cu × 1mol Cu 63.55g Cu = 0.3934 mol Cu. Moles of O = 0.63 g O × 1mol O 16.00g O = 0.394 mol Cu. Step 3. Determine the Molar Ratios. Moles of Cu Moles of O = 0.3934mol 0.394mol = 1 1.00 ≈ 1 1. Step 4. Write the Empirical Formula. WebThe specific heat capacity is the amount of heat it takes to change the temperature of one gram of substance by 1°C. So, we can now compare the specific heat capacity of a substance on a per gram bases. This value also depends on the nature of the chemical bonds in the substance, and its phase. q = mc Δ T, c = q ( J) m ( g) Δ T ( K) Note ... WebSo we're going to need 0.833 moles of molecular oxygen. And then I just multiply that times the molar mass of molecular oxygen. So, times 32.00 grams per mole of molecular oxygen. 0.833 times 32 is equal to that. If you go three significant figures, it's 26.7. 26.7 grams of oxygen, of molecular oxygen. chicken 6-0s pixel game
