Looking at the reaction,

1 mole of SiO2 reacts with 3 moles of C to form 1 mole of SiC and 2 moles of CO

So the ratios are : SiO2 : C : SiC : CO = 1 : 3 : 1 : 2

Completed Table below,

molSiO2    molC    molSiC    molCO

    3               9            3            6

    3               9            3            6

   15             45          15          30

   2.5            7.5         2.5        5.0   

   2.4            7.2         2.4        4.8
