Find the number of g atoms and weight of...

Find the number of g atoms and weight of an element having `2 xx 10^(23)` atoms. Atomic mass of element is 32.

A

0.22g atom, 9.2 g

B

0.22g atom, 8.2 g

C

0.33g atom, 10.6 g

D

0.33g atom, 9.6g

Verified by Experts

The correct Answer is:

C

Number of g atoms `= (2 xx 10^(23))/(6 xx 10^(23)) = 0.33`, Weight `= 0.33 xx 32 = 10.6g`
