Read to the end and tell us your idea about the post.
Thank you & hope to see you soon again.
First find the molar mass of C10H14N2 by multiplying the number of atoms of each element times its molar mass (atomic weight on the Periodic Table). Then add the molar masses of each element. The sum is the molar mass of the compound.
C: 10 x 12.011g/mol = 120.11g/mol
H: 14 x 1.008g/mol = 14.11g/mol
N: 2 x 14.007g/mol = 28.014g/mol
Total = 162.23g/mol = molar mass of C10H14N2
Percent carbon by mass = mass of C/mass of C10H14N2 x 100 = (120.11g/mol)/(162.23g/mol) x 100 = 74.037% C by mass

What is the percent by mass of carbon in c10 h14?
- which of the following is the most expensive premium mode overall
- which of these statements accurately describes an mtoc?
- how much is 21.50 dollars an hour annually
- when was declaration of independence adopted
- the time has come the walrus said lyrics
- what does the number 3 stand for in the bible?
Step 1: Find the mass of the individual atoms. Look up the atomic masses for carbon and oxygen from the Periodic Table.
- mass % C = (mass of 1 mol of carbon/mass of 1 mol of CO2) x 100.
- So mass % C = (12.01 g / 44.01 g) x 100.
- mass % C = 27.29 %
