Web12 aug. 2024 · The molar mass of helium is 4.0 grams per mole. Helium is a monatomic gas with a low boiling point and a low melting point. It is the second lightest element and is the second most abundant element in the universe after hydrogen. Helium is used in welding, diving, and in pressurizing fuel tanks in rocketry. Web18 mei 2024 · The number of atoms in 2 moles of helium is 1.204×10²⁴ atoms. From Avogadro's hypothesis, 1 mole of any substance = 6.02×10²³ atoms. Thus, 1 mole of helium = 6.02×10²³ atoms. With the above information in mind, we can obtain the number of atoms in 2 moles of helium as follow: 1 mole of helium = 6.02×10²³ atoms. Therefore, Web28 mrt. 2024 · N u m b e r o f m o l e s = 52 4. The number of moles= 13g. Hence the moles present in the 52g of He are 13 Additional Information. Helium : It is a noble gas.
