WebThe number of molecules in 1 kg of nitrogen gas sample (molar mass = 28 g/mol) is approximately: A 2.15×1025 B 3.6×1023 C 8.06×1023 D 4.08×1022 Solution The correct option is A 2.15×1025 1 mole of nitrogen or 28 g of nitrogen contains 6.023×1023 molecules of nitrogen. Thus, 28 g of nitrogen contain molecules = 6.023×1023 WebConvert molar mass of O2 molecules to kg per mole: M (in kg mole) = 32.00 g molex 1 kg 1000 g = 0.03200 kg mole Use equation 27.1.16 to calculate the rms speed. Solution vrmsO2 = √3(8.3145 J K · mole)(298.15 K) 0.03200 kg mole = 482m s Exercise 27.1.2 What is the root mean-square speed for Cl2 molecules at 25ºC? vrmsCl2 = 324m s tarif retrait orange money madagascar
Molar Mass / Molecular Weight of N2: Nitrogen Gas
WebDensity is the mass of a substance that would fill 1 cm 3 at room temperature. Relative atomic mass The mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average.
