Answer:
Think sorry if i did it wrong The molar mass that is the mass of 6.022 X 1023 atoms of helium is 4g. Hence 1 mole of He = 4 g of He = 6.022 X 1023atoms of He. 1 g of He = (6.022 X 1023) / 4 atoms of He. 52 g of He = (6.022 X 1023X 52 ) / 4 atoms of He.
For Helium,
Number of atoms=Number of moles ×6.022×1023
No of Moles = 6.022×10
2312.044×10
23 = 2.
Now, atomic mass of He=4
Weight = 2×4 = 8 g
The molar mass that is the mass of 6.022 X 1023 atoms of helium is 4g. Hence 1 mole of He = 4 g of He = 6.022 X 1023atoms of He. 1 g of He = (6.022 X 1023) / 4 atoms of He. 52 g of He = (6.022 X 1023X 52 ) / 4 atoms of He.
As we know, gram atoms = gram mole
here, no of moles = 23/46 =2 so no of gram atoms are 2.
