8co + 17h2 → c8h18 + 8h2o

in this chemical reaction, how many grams of h2 will react completely with 6.50 moles of co?

27,625 grams

Explanation:

*This is actually pretty simple

According to your equation, we know that:

8 moles of CO will react completely with 17 moles of H2

so:

6.50 moles of Co will react completely with x moles of H2

x= (6.50 x 17)/8 = 13.8125 (moles)

Since the Molar Mass of H2 is 2 g/mol, we can calculate the amount of H2 needed to react completely with 6.50 moles of CO:

=>13.8125 x 2= 27.625 (grams)
