How many grams of carbon monoxide can be obtained from 360 grams of carbon?

Let us write down the reaction equation for obtaining carbon monoxide (since the condition does not indicate a specific oxide, we believe that we get carbon monoxide (ll) from carbon):

2С + O2 = 2CO

According to the reaction equation, the amounts of C and CO are 1: 1

Now we find the amount of C: 360 (g) / 12 (g / mol) = 30 (mol)

Now we find the mass of CO: 30 (mol) * 28 (g / mol) = 840 (g)
