A. 2 : 1

B. 1 : 8 

C. 8 : 1 

D. 1 : 2

the mass of hydrogen is 1.0, the mass of carbon is 12.0, the mass of oxygen is 16.0, and the chemical formula for glucose is C6H12O6. what is the molarity of a 10% glucose C6H12O6 what is the molarity of a 10% glucose solution.

132. Which answer is an example of the law of multiple proportions? Explain. a. Two different samples of water are found to have the same ratio of hydrogen to oxygen. b. When hydrogen and oxygen react, the mass of water formed is exactly equal to the mass of hydrogen and oxygen that reacted. c. The mass ratio of oxygen to hydrogen in water is 8:1. The mass ratio of oxygen to hydrogen in hydrogen peroxide (a compound that only contains hydrogen and oxygen) is 16:1.

b). There are two hydrogen atoms and one oxygen atom per water molecule.

c). There is twice as much mass of oxygen as hydrogen in each molecule.

d). There are two oxygen atoms and one hydrogen atom per water molecule.
