Question

answer the above question with explanation​

Answer 1

1. The atomic mass unit of the helium He atom is four (4) atomic mass units. Hence, The number of atoms of the He in 104 amu is 26.

2. The atomic mass of Helium is 4 u. Therefore, its molar mass is 4g. This means that the mass of 6.023 X 1023 atoms of He is 4g. Thus there are 6.023 X 1023 atoms in 4 g of He.
