According to the Law of Conservation of Mass, if 88 g of carbon dioxide ( CO2 ) is produced in a reaction between oxygen (O) and 24 g of carbon (C), what is the mass of dioxygen ( O2 ) in the reactants?

Question

24 g 24 g 64 g 64 g 104 g 104 g 32 g

Answer 1

The reaction between oxygen (O) and carbon (C) to produce carbon dioxide (CO2) can be represented as follows:

C + O2 -> CO2

According to the Law of Conservation of Mass, the total mass of the reactants should be equal to the total mass of the products. Therefore, we can set up the following equation to solve for the mass of dioxygen (O2) in the reactants:

Mass of carbon (C) + Mass of dioxygen (O2) = Mass of carbon dioxide (CO2)

From the given information, we know that the mass of carbon dioxide (CO2) produced is 88 g, and the mass of carbon (C) used is 24 g. Let's use x to represent the mass of dioxygen (O2):

24 g + x = 88 g

Solving for x:

x = 88 g - 24 g
x = 64 g

Therefore, the mass of dioxygen (O2) in the reactants is 64 g.
