Question

Find the mass of 1.5*10^23 ATOMS OF NEON

Answer 1

Answer:

4.98g

Explanation:

atomic mass of Ne= 20 g/mol

6.022×10^23 atoms of Ne = 20g

1.5× 10^23 Atoms of Ne = 4.98g

Answer 2

Answer:

3488 g

Explanation:

Number of Moles= Given Mass/Molar Mass

1 mol of atoms  =

6.022  ×  10  ^23  atoms

1.05  ×  10

^26  atoms is equal to

1.05 ×  10^

26  atoms  ×  1 mol  / 6.02  ×

10

^23  

atoms  =  174.4 mol  

Molar mass of neon is  20 g/mol

Mass of  174.4 mol  atoms of neon is

174.4  mol  ×  20  x g /  mol  =  3488 g

Hope it helps :)
