Question

The mass of carbon in 1.00 mol of sucrose is:

Answer 1

What's the chemical formula for sucrose?

Answer 2

C12H22O11

Answer 3

i know the answer (144g) i just don't know how to get there

Answer 4

Do you know how to find the mass on the periodic table for an element?

Answer 5

yes

Answer 6

Awesome, what is it for carbon, since that's what we're interested in here.

Answer 7

do u know the molar mass of sucrose?

Answer 8

molar mass of sucrose is 212.16 and carbon is 12.01

Answer 9

yes good

Answer 10

how do i go from there?
26% of the total mass would be carbon, right?

Answer 11

1 MOLE OF SUCROSE MEANS 342 G OF SUCROSE

Answer 12

NO UR RIGHT ITS 342.34

Answer 13

AND IF YOU OBSERVE THE CHEMICAL FORMULA OF COMPOUND ULL SEE THAT IN 1 MOLE OF THE COMPOUND THERE ARE 12 MOLES OF CARBON

Answer 14

SO MASS OF CARBON= ATOMIC MASS*NO. OF MOLES=12*12=144

Answer 15

THANK YOU SOOOO SOOO MUCH!!!

Answer 16

pleasure! :)
