27.1 g of SiC are formed by the reaction

Explanation:

The silicium carbide is formed according to the reaction of Carbon and silicium dioxide. We also can produce carbon monoxide at the reaction.

The equation is:

SiO₂ + 3C → SiC + 2CO

According to the stoichiometry we can prodouce 1 mol of silicium carbide, from 3 moles of carbon so we may propose this rule of three:

3 moles of C can produce 1 mol of SiC

Then 2 moles of C, will produce ( 2 . 1) /3 = 0.666 moles of SiC

We conver the moles to mass (mol . molar mass) =

0.666 mol . 40.1 g / 1 mol = 26.7 g
