what are the equivalent weights of glucose and co2 for equation 6CO2 + 12H2O → C6H12O6 + 6O2 +6H2O
Sauron [17]
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.

90 grams of glucose, C6H12O6, is dissolved in 2 liters of solution. Determine the molarity (M).
Masja [62]

Answer:

0.25 M

Explanation:

The first step is to determine how many moles of glucose there are, which means first finding out the molar mass of glucose. Carbon has a molar mass of about 12, hydrogen 1, and oxygen 16, so the total molar mass of glucose is about 6(12)+12(1)+6(16)=180 grams. This means that 90 grams is half a mole. Half a mole of substance divided by two liters of solution is (1/2)/2=1/4, or a molarity of 0.25. Hope this helps!

11 a- ions would exist in the solution, they can carry charges.

B-solids that are neutral, they wouldn't conduct much of a current.
