Question

Number of atoms present in 52 g of Helium is ?
1) 26 x N
2) N
3) 52 N
4) 13 * N
Atomic mass of silicon is 28 g, how many silicon atoms are there in 1.00 g of silicon ?
pls guyzz answer me fast....​

Answer 1

Answer:

1) 26 x N

And

Number of silicons atoms present in 1 g silicon = N/28

Explanation:

Number of atoms = Moles x N

AND

Moles = Given mass/ Molecular mass
