Question

What is the mass of 6.02×1022 6.02 × 10 22 atoms of argon?

Answer 1

3.6 g

Step-by-step explanation:

No. of moles = No. of atoms / Avogadro's No.

= 6.02 × 10^22 / 6.02 × 10^23

= 0.1 moles of argon

No. of moles = mass/ molar mass

molar mass of argon = 36 g/mol

Therefore, mass of argon = No. of moles × molar mass

= 0.1 × 36

= 3.6 g of argon
