Molar mass :
HC₂H₃O₂ = 1 + 12*2 + 1 * 3 + 16 * 2 = 60 g/mol
1 mole <span>HC₂H₃O₂ -------------- 60 g
</span>1.26x10-⁴ mole ----------------- mass
mass = 1.26x10-⁴ * 60
mass = 0.00756 g of <span>HC₂H₃O₂</span>
hope this helps!
Answer:
The overall charge of an atom is zero. Atoms are made up of positively charged particles called protons and negatively charged particles called electrons as well as non-charged particles called neutrons.

Carbon dioxide consists of the elements Carbon (C) and Oxygen (O) and you have to have 2 oxygen.
Partial mass of C, 12*2 = 24
Partial mass of H, 1*5 = 5
Partial mass of N, 14
Partial mass of O, 16
Now, total molar mass would be 24+5+14+16 = 59
mass % of carbon = 24 * 100 / 59 = 40.67%
