Question

rearrange the following (I to Iv) in the order increasing masses and choose the correct answer (Atomic masses:N=14,O=16,Cu=63)​

Answer 1

Answer:

Correct sequence will be:

                         II < I < III < IV  

One atom of N2 < one molecule of O2 < 1 × 10e-10 grams molecular mass of O2 <  1 × 10e−10 grams atomic weight of Cu

Explanation:

I. One molecule of O2

II. One atom of N2

III. 1 × 10e-10 grams molecular mass of O2

IV. 1 × 10e−10 grams atomic weight of Cu

One atom of N2 < one molecule of O2 < 1 × 10e-10 grams molecular mass of O2 <  1 × 10e−10 grams atomic weight of Cu
