Answer:
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.

Answer:
78.28×10to the power 23. atom
Explanation:
1 mole of he contain =6.022×10. to the power 23 particles = molar mass (4g)
no of atom in 52g He =52×6.022×10to the power 23/4
= 78.28×10 to the power 23 atom.
