The number of roles in 2x 10 4 atome
on are:​

Answer 1

Explanation:

i hope the question is number of moles of 2×10^4 atoms

to calculate number of moles use formula

n = given number of atoms ÷ avagadro number of atoms

avagadro number = 6 × 10^23

now nomber of moles n = (2× 10^4 ) ÷ (6×10^23)

by simplying it you get n = 3.3×10^-20
