Question

Given: 8CO + 17H2 → C8H18 + 8H2O In this chemical reaction, how many grams of H2 will react completely with 6.50 moles of CO? Express your answer to three significant figures. _______ grams of H2 will react completely.

Answer 1

Answer:

Explanation:

Here in this reaction we use weight-weight relationship concept i.e

8moles CO reacts with 17 moles of H2 then 6.5 moles of CO react with

6.5×(17/8) moles of H2 i.e 13.8 moles of H2. weight of H2 required is 13.8* molar mass of H2

=2*13.8 = 27.6g

Weight of H2 required is 27.6 gr
