🤓 Based on our data, we think this question is relevant for Professor Van Dorn's class at ARIZONA.

Solution: A 2.3-g sample of carbon dioxide (CO2) is fully decomposed into its elements, yielding 0.628 g of carbon and 1.67 g of oxygen.If a sample of a different compound decomposes into 0.429 g of carbon and 0.571 g of oxygen, what is its ratio of the mass of O to C?

Problem

A 2.3-g sample of carbon dioxide (CO2) is fully decomposed into its elements, yielding 0.628 g of carbon and 1.67 g of oxygen.

If a sample of a different compound decomposes into 0.429 g of carbon and 0.571 g of oxygen, what is its ratio of the mass of O to C?

Solution
  • The ratio of the mass of O to C can be calculated by dividing the mass of oxygen by the mass of C
