Arrange the following in order of decreasing mass
(i) 1 F atom
(ii) 1 N atom
(iii) 1 O atoms
(iv) 1 H atom

Options

A. (a)`igt iiigt ivgt ii`
B. (b)`ivlt iilt iiilt i`
C. (c )`igt iiigt iigt iv`
D. (d)`iiigt igt iigt iv`

Answer

c

Explanation

Mass of 1F atom`=19/(6.023xx10^(23))("since At. Wt. of F=19")`
Mass of 1N atom `=14/(6.023xx10^(13))`, Mass of 1 H atom `= 1/(6.023xx10^(23))`
Mass of 1 o atom`=16/(6.023xx10^(23))`
`igt iiigt iigt iv`
