SiO2 + 3C - SiC + 2CO

I need to add 8 moles of Carbon to the reaction. How many grams of Carbon should I

weigh?

96g

Explanation:

To know the exact mass of carbon (C) to add to the reaction, we need to convert 8 moles of carbon (C) to grams.

This is illustrated below:

Molar mass of C = 12g/mol

Number of mole of C = 8 moles

Mass of C = ... ?

Mass = number of mole x molar mass

Mass of C = 8 x 12

Mass of C = 96g

Therefore, 96g of carbon (C) is needed.
