Question

Aluminum and tin are both metals. The standard atomic weight for aluminum is 26.98. The standard atomic weight for tin is 118.71.Estimate the difference between the standard atomic weights of these two metals

Answer 1

92

Explanation:

To estimate the difference between the standard atomic weights of these two metals we round up the given weights to the nearest whole number

The standard atomic weight for aluminum is 26.98.

To the nearest the whole number = 27

The standard atomic weight for tin is 118.71

To the nearest whole number = 119

Hence,

The estimated difference = 119 - 27

= 92
