The element whose one atom has mass of `10.86xx10^(-26)` 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

Text Solution

Verified by Experts

The correct Answer is:
D
1 atom has mass `= 10.86 xx 10^(-26) kg `
` = 10.86 xx 10^(-23)g `
`6.022 xx 10^(23) ` atoms has
mass `= 10.86 xx 10^(-23) xx 6.022 xx 10^(23) = 65.40 g`
This is the atomic weight of Zn.
