Carborundum is silicon carbide, SiC, a very hard material used as an abrasive on sandpaper and in other applications. It is prepared by the reaction of pure sand, SiO2, with carbon at high temperature. Carbon monoxide, CO, is the other product of this reaction. The balanced equation is shown below. How many grams of the carbon monoxide side product are produced from 6.41 moles of SiO2? Show all work and round your answer to three significant figures. SiO2 + 3C → SiC + 2CO
