The empiracal formula for Vitamin C is C3H4O3 and the Molecular Formular is C3(2)H4(2)O3(2) which is C5H8O6, and the molecular mass is 176.
I hope this helps
Please click on EXCELLENT Service (smile face)
I see I put C5H8O6 - -----change that to C6H8O6
Total mass of C3H4O3 = (12 x 3) + (4 x 1) + (16x 3) = 88 and hence with the Molecular formula of C3(2)H4(2)O3(2) = C6H8O6*1 + 16*3 = 88 176 / 88 = 2 Therefore molecular formula =
Then 88 x 2 = 176
Do you have any more questions?
Carbon = C = 12
Oxygen = 16
Hydrogen = 1
Did you have any additional questions?
You asked for the Empiral formula - that is C3H4O3
that was part one
Then part B - the question was what is the Molecular formula - that is C3(2)H4(2)O3(2) = C6H8O6
Then to calculate the molar mass
here is the work for that:
Yes they are subscripts
Sorry I can not put that here on this website like that
subscripts do not work on the website - I wish they did
Hello - I'm still here
Are you there?
