Arrange the following (I to IV) in the increasing order of their masses and choose the correct answer.
(I) 1 atom of oxygen.
(II) 1 atom of nitrogen.
(III) molecule of oxygen.
(IV) atom of copper.
Options:
Answer:
A
Solution:
(I) Mass of one oxygen atom = gm
(II) Mass of one nitrogen atom = gm
(III) Since 1 gm molecule of oxygen = 32 g,
1 10⁻¹⁰ gm molecule of oxygen = gm
(IV) Since 1 gm atom of Cu = 63.5 g,
1 10⁻⁷ gm atom of Cu = gm
