What is the molar mass of a gas if 0.0494 g of the gas occupies a volume of 0.100 L at a temperature 26 °C and a pressure of 307 torr? If a 0.064 g sample of CaC2 (s) (molar mass 64 g/mol) is used instead and all of it reacts, which of the following will occur and why? When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Weights of atoms and isotopes are from NIST article. This page was last edited on 5 December 2020, at 18:04. Molar mass of CaC2 = 64.0994 g/mol This compound is also known as Calcium Carbide.. Expression of molar mass is grams per mole. To complete this calculation, you have to know what substance you are trying to convert. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. 4 g  = 0.895 moles. So divide 32 by 40.078 + (2*12.011) (You multiply by two because there are two carbon molecules.) It was the very first power station of its kind in Southeast Europe, which became operational on 24. Get answers by asking now. What is the actual mass of vitamin C in the tablet? Calcium Carbide (CaC2) - Calcium Carbide is a colorless and odorless solid. as a fuel in steelmaking to extend the scrap ratio to liquid iron, depending on economics. The impurities are concentrated in the finer fractions. A) 1.30 × 10–5 g D) 1.56 × 10 –4 g B) 6.43 × 10 3 g E) 12.01 g C) 7.80 × 10 18 g Ans: D Category: Medium Section: 3.2 14. 0.499 mol CaC2 x (2 mol H2O / 1 mol CaC2) = 0.998 mol H2O. The molar mass of CaC2 = 64.1 g/mol. 40.078 + 12.0107*2, Note that all formulas are case-sensitive. 2. of a chemical compound, More information on Did you mean CaC2?
