Calculate number of atoms in 52 g of helium ??

1.	Calculate number of atoms in 52 g of helium ??
Answer» Hi there! The molar mass that is the mass of 6.022 × $10^{23}$ atoms of HELIUM is 4g. Hence 1 mole of He = 4 g of He = 6.022 × $10^{23}$ atoms of He 1 g of He = (6.022 × $10^{23}$ ) / 4 atoms of He 52 g of He = (6.022 × $10^{23}$ × 52 ) / 4 atoms of He = 7.829 × $10^{24}$ atoms of Helium [ He ] Hope it HELPS! :D Cheers, Ishaan SINGH
