Question

13.8 g element consist 4.6 × 10^22 atoms what is atomic mass of element?​

Answer 1

Answer:

180.6 g

Explanation:

Given, 13.8 g of an element contains 4.6 × 10²² atoms.

Then the weight of 1 atom = 13.8/4.6 ×10²²

                                              = 3 /10²²

Atomic mass of element = weight of 1 atom × avogadro number

= 6.02×3×10¹

= 180.6 g
