Question

A solution contains 5 grams of glucose per 100 milliliters. Each mole of glucose weighs 180 grams. How many moles are there in 200 milliliters of the glucose solution?

Answer 1

Answer:

0.055

Step-by-step explanation:

Given A solution contains 5 grams of glucose per 100 milliliters. Each mole of glucose weighs 180 grams. How many moles are there in 200 milliliters of the glucose solution

100 ml will contain 5 gms of glucose in a solution

so for 200 ml =  200 x 5 / 100 = 10 gms of glucose in a solution.

180 gms will weigh one mole of glucose

Therefore 10 gms will weigh = 10 / 180 = 0.055 moles

In 200 ml there are 0.055 moles.
