The weight of one molecule of a compound of molecular formula C60H122 is (a) 1.2 × 10–20 g (b) 5.025 × 1023 g (c) 1.4 × 10-21 g (d) 6.023 × 10-20 g

(c) 1.4 × 10-21 g Explanation: M.W. = 60 × 12 + 122 = 842 Weight of one molecule = 842/6.02 x 1023 gm = 140 x 10-23gm = 1.4 × 10-21 gm

Explanation:

M.W. = 60 × 12 + 122 = 842

Weight of one molecule = 842/6.02 x 10²³gm

= 140 x 10^-23gm = 1.4 × 10^-21 gm
