Question

Complete combustion of 1.8g of an oxygen-containing compound (CxHyOz) gave 2.64g of CO2 and 1.08g of H2O. The percentage of oxygen in the organic compound is:

a. 30%
b. 40%
c. 50%
d. 60%

Answer 1

The mass of oxygen in the compound cannot be determined with the given information.

Step-by-step explanation:

To determine the percentage of oxygen in the organic compound, we need to calculate the mass of oxygen in the compound.

Given that the complete combustion of 1.8g of the compound produced 2.64g of CO2 and 1.08g of H2O, we can calculate the mass of oxygen by subtracting the masses of carbon and hydrogen from the total mass:

Mass of oxygen = Total mass - (Mass of carbon + Mass of hydrogen) = 1.8g - (2.64g + 1.08g) = 1.8g - 3.72g = -1.92g

Since the resulting mass is negative, it indicates an error in the given information. Please check the values provided and try again.
