Given: 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 solution?

The answer to your question is: 0. 55 M

Explanation:

Data

H = 1

C = 12

O = 16

MW of glucose = (1x12) + (12x 6) + (16x6) = 12 + 72 + 96 = 180 gr

We have a solution 10% of glucose that means 10 g of glucose and 100 ml of solution

Also Molarity = # moles / liters

                             180 g of glucose 1 mol

                               10 g     x

x = 10 x 1/180 = 0.055 moles

Molarity = 0.055 /0.1 liters = 0.55 M

law of conservation of matter

i'm assuming that the correct answer is indeed the first one/ "a"..
