What are the equivalent weights of glucose and co2 for equation 6co2 + 12h2o → c6h12o6 + 6o2 +6h2o

For this reaction, the mass of carbon dioxide and glucose involved are the product of thier molar mass and the number of moles of each compound involved in the reaction. 
                    carbon dioxide:   6 x (12 + 2 x 16) = 264
                        glucose       :   1 x (6 x 12 + 12 + 6 x 16) = 180
Divide their masses to get the equivalent weights. The answer is 22/15 or 11/7.5. 

Yes i think so not 100 percent sure though
