Question

The molecular formula mass of this compound is 240 amu . What are the subscripts in the actual molecular formula?

Answer 1

Does it give you the empirical formula?

Answer 2

Continuation of part A

Answer 3

Oh then just find the molar mass of CH2O

Then, dividing 240/molar mass of CH2O will tell you how much to multiply the subscripts by

Answer 4

Ex: if 240/molar mass of CH2O gives you 3, then CH2O becomes C3H6O3 (this isn’t the solution just giving an example)

Answer 5

30.031

Answer 6

is the molar mass

Answer 7

so divide that by the amu given?

Answer 8

Yes, then 240/30.031 is about 8

Answer 9

So multiply CH2O by 8

Answer 10

okay so 8 C 16 H and 24 O

Answer 11

8 O

Answer 12

Hm not quite

Only 1 oxygen atom on CH2O so C8H16O8

Answer 13

sorry

Answer 14

Anyway I gotta get to class but I’ll probably be on tonight
