Question 15

Copper(II) oxide reacts with carbon to produce copper and carbon dioxide. The ratio of the masses of copper(II) oxide and carbon that react is:

copper(II) oxide:carbon=53:4 \text{copper(II) oxide} : \text{carbon} = 53 : 4 copper(II) oxide:carbon=53:4

Calculate the mass of copper(II) oxide that reacts completely with 6 g6\text{ g}6 g of carbon.
