Answer
The mass of copper oxide produced when 0.50 g of copper reacts with oxygen is 0.626 g, to 3 significant figures.
Explanation
## Step 1: The first step in solving this problem is to determine the ratio of the mass of copper oxide produced to the mass of copper used. This ratio can be calculated using the given data from the problem.### The ratio of the mass of copper oxide to the mass of copper is given by the formula: ###
## Step 2: The ratio of the mass of copper oxide to the mass of copper is calculated as: ###
## Step 3: Next, we can use this ratio to calculate the mass of copper oxide that would be produced when 0.50 g of copper reacts with oxygen. ### The mass of copper oxide produced is given by the formula: ###
## Step 4: The mass of copper oxide produced is calculated as: ###
