Answer:

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
