A 1.00 g sample of naphthalene (C10H8) contains 0.562 g of hydrogen. What is the mass percent of carbon in the compound
Neat trick if you can do it.
How can a 1.00 sample of anything contain 0.562g of a subpart.
What is the percent composition of carbon in glucose (C6H12O6)?
(The molar mass of C = 12.01, H = 1.0079 and O = 16.00.)
43.8
To find the mass percent of carbon in the compound, we need to determine the mass of carbon and divide it by the total mass of the compound, and then multiply by 100 to get the percentage.
Given data:
Mass of naphthalene (C10H8) = 1.00 g
Mass of hydrogen in naphthalene = 0.562 g
To calculate the mass of carbon, we can first calculate the mass of hydrogen in the compound since we are given that value.
Mass of carbon = Total mass of naphthalene - Mass of hydrogen in naphthalene
Mass of carbon = 1.00 g - 0.562 g = 0.438 g
Next, we can calculate the mass percent of carbon in the compound using the formula:
Mass percent of carbon = (Mass of carbon / Total mass of compound) × 100
Mass percent of carbon = (0.438 g / 1.00 g) × 100
Mass percent of carbon = 43.8%
Therefore, the mass percent of carbon in the compound is 43.8%.
