Question
The weight of one molecule of a compound of molecular formula C60H122 is
Options
A.1.2 × 10-20 g
B.5.025 × 1023 g
C.1.4 × 10-21 g
D.6.023 × 10-20 g
Solution
M.W. = 60 × 12 + 122 = 842
Weight of one molecule =
gm
= 140 × 10-23 gm = 1.4 × 10-21 gm
Weight of one molecule =
gm= 140 × 10-23 gm = 1.4 × 10-21 gm
