A) Boron
B) Calcium
C) Silver
D) Zinc
Correct Answer: D
Solution :
1 atom has mass \[=10.86\times {{10}^{-26}}kg\] \[=10.86\times {{10}^{-23}}gm\] \[6.023\times {{10}^{23}}\]atoms has mass =\[10.86\times {{10}^{-23}}\times 6.023\times {{10}^{23}}\] = \[65.40gm\] This is the atomic weight of Zn.You need to login to perform this action.
