Answer:
The percentage composition if carbon tetrahydride is 75% of carbon and 25% of hydrogen.
Explanation:
Molecular mass of carbon tetrahydride = 16 g/mol
Atomic mass of carbon = 12 g/mol
Atomic mass of hydrogen atom = 1 g/mol
Percentage of an element in a compound:
[tex]\frac{\text{Number of atoms of element}\times \text{Atomic mass of element}}{\text{molecular mass of element}}\times 100[/tex]
Percentage of carbon:
[tex]\frac{1\times 12 g/mol}{16 g/mol}\times 100=75\%[/tex]
Percentage of hydrogen:
[tex]\frac{4\times 1g/mol}{16 g/mol}\times 100=25\%[/tex]
The percentage composition if carbon tetrahydride is 75% of carbon and 25% of hydrogen.
