Question

number of atoms present in 4g he​

Answer 1

Answer:

the answer will be 1) The molar mass that is the mass of 6.022 X 1023 atoms of helium is 4g. 

1) 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 1023 atoms of  He.

Answer 2

Answer:

Explanation:

 The molar mass that is the mass of 6.022 X 1023 atoms of helium is 4 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 1023 atoms of  He.
