Question

2.770 g sample of a compound containing only Carbon, Hydrogen, and Oxygen burns in excess Oxygen to produce 4.06 g of CO₂ and 1.66 g of H₂O.

Calculate the mass (in g) of c in the sample.

Answer 1

To calculate the mass of carbon in the sample, divide the mass of CO₂ by its molar mass.

Step-by-step explanation:

First, we need to determine the mass of carbon in the sample. From the given information, we know that 4.06 g of CO₂ is produced when the sample is burned. Since CO₂ contains one carbon atom, we can calculate the mass of carbon in the sample by dividing the mass of CO₂ by its molar mass:

Mass of carbon = Mass of CO₂ / Molar mass of CO₂

Next, plugging in the values:

Mass of carbon = 4.06 g / 44.01 g/mol

Finally, we can calculate the mass of carbon in the sample:

Mass of carbon = 0.0924 g
