How many atoms present in one mole of helium
Answered by admin @
Explanation:
1 He molecule contains only 1 atom(as helium is monoatomic). So, 1 mole He gas contains 2x6.023x10^23 He atoms. 1 mole Of Helium = Weight of Helium/4Weight of Helium = 1*4 = 4 grams 1 mole of Helium contains 6.023*10²³ (Avogadro number) atoms. one mole is equilant to Avogadro's number 6.02x10^23 particles.
