Question

Question:The Element whose one atom has of 10.86×10^-23 kg is (Atomic masses:B=10.8 u,Ca=40 u,Ag=107.8 u,Zn=65.4 u)

A) Boron
B) Calcium
C) Silver
D)Zinc​

Answer 1

Answer:

zinc

Explanation:

1 atom has mass =10.86×10−²³ kg

=10.86×10−²³ gm

6.023×10²³

atom has mass

=10.86×10−²³×6.023×10²³

=65.40gm

This is the atomic weight of Zn.
