WebAug 13, 2024 · The molar mass of any compound is the mass in grams of one mole of that compound. One mole of carbon dioxide molecules has a mass of 44.01g. The molar mass is 44.01g/mol for CO 2. For water, the molar mass is 18.02g/mol. In both cases, it is the mass of 6.02 × 1023 molecules. Example 2.3.5. WebJan 22, 2024 · (iv) 2 moles of B produces 1 mole of C (v) 1 mole of C is produced by 1 mole of A and 2 moles of B. Therefore to find the number of moles of C produced by 2 mole of B we will do following proportional method. As, 2 moles of B produced = 1 mole of C. So, 2 moles of B will produce = X moles of C. Solving for X,
WebYes, if you were dealing with an ideal gas the ideal gas law would still apply which could be used to calculate (in addition to number of moles) temperature, pressure, and volume of the gas. Since the ideal gas law is: PV = nRT, it has four variables (P, V, n, and T), we would need to know three of the four to calculate the fourth variable.
