Question

Which of the following is not equal in mass to the 116th part of an oxygen atom? (a) 14th of helium atom (b) 112th of carbon atom (c) 128th of nitrogen atom (d) None of these​

Answer 1

Explanation:

14th of helium atom is the answer

Answer 2

Answer:

14th of Helium atom does not equal in mass to the 116th part of Oxygen atom.

Explanation:

Calculating 116th part of Oxygen atom

We know the atomic mass of Oxygen is 8

=> $\frac{1}{116}$ * 8

≈ 0.06

(a) 14th part of Helium atom

We know the atomic mass of Helium is 2

=> $\frac{1}{14}$ * 2

≈ 0.14

(b) 112th part of Carbon atom

We know the atomic mass of Carbon is 6

=> $\frac{1}{112}$ * 6

≈ 0.05

(c) 128th part of Nitrogen atom

We know the atomic mass of Nitrogen is 7

=> $\frac{1}{128}$ * 7

≈ 0.05

As 0.06 ≈ 0.05

Therefore, options (b) and (c) equals the given condition.

Therefore, 14th of Helium atom does not equal in mass to the 116th part of Oxygen atom.

Therefore, option (a) is the correct option.
