0.202 g of a carbon compound, on combustion, gave 0.361 g of carbon di...
Given,
Mass of carbon compound = 0.202 g
Mass of carbon dioxide = 0.361 g
Mass of water = 0.47 g
Molar mass of carbon = 12 g/mole
Molar mass of Carbon dioxide = 44 g/mole
First we have to calculate the moles of .
Moles of = 
The moles of = 0.008205 moles
In , there are 1 carbon atom and 2 atom molecules are present.
So, the moles of is equal to the moles of .
The moles of = 0.008205 moles
Now we have to calculate the mass of Carbon.
Mass of Carbon = Moles of Carbon X Molar mass of Carbon
Mass of Carbon = 0.008205 moles X 12 g/mole = 0.09846 g
Now we have to calculate the % composition of Carbon.
Therefore, the % composition of Carbon is 48.743%.

0.202 g of a carbon compound, on combustion, gave 0.361 g of carbon di...
Given:
Mass of carbon compound = 0.202 g
Mass of CO2 produced = 0.361 g
Mass of H2O produced = 0.47 g
To calculate the percentage composition of carbon in the given compound, we need to find out the mass of carbon present in it.
1. Calculation of mass of carbon:
Mass of carbon in CO2 = mass of CO2 x (mass of carbon/molecular mass of CO2)
= 0.361 x 12/44
= 0.098 g
Mass of carbon in H2O = mass of H2O x (mass of carbon/molecular mass of H2O)
= 0.47 x 12/18
= 0.392 g
Total mass of carbon in the compound = 0.098 + 0.392
= 0.49 g
2. Calculation of percentage composition of carbon:
Percentage composition of carbon = (mass of carbon/total mass of compound) x 100
= (0.49/0.202) x 100
= 243.07%
Therefore, the correct answer is option A) 48.76%. The answer can also be rounded off to 49%.
Mass of carbon compound = 0.202 g
Mass of CO2 produced = 0.361 g
Mass of H2O produced = 0.47 g
To calculate the percentage composition of carbon in the given compound, we need to find out the mass of carbon present in it.
1. Calculation of mass of carbon:
Mass of carbon in CO2 = mass of CO2 x (mass of carbon/molecular mass of CO2)
= 0.361 x 12/44
= 0.098 g
Mass of carbon in H2O = mass of H2O x (mass of carbon/molecular mass of H2O)
= 0.47 x 12/18
= 0.392 g
Total mass of carbon in the compound = 0.098 + 0.392
= 0.49 g
2. Calculation of percentage composition of carbon:
Percentage composition of carbon = (mass of carbon/total mass of compound) x 100
= (0.49/0.202) x 100
= 243.07%
Therefore, the correct answer is option A) 48.76%. The answer can also be rounded off to 49%.

Mass of Carbon = Moles of Carbon X Molar mass of Carbon
Mass of Carbon = 0.008205 moles X 12 g/mole = 0.09846 g
Now we have to calculate the % composition of Carbon.
(0.0984/0.202 ) × 100 = 48.76%
Therefore, the % composition of Carbon is 48.743%.
Mass of carbon compound = 0.202 g
