Question

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

Answer 1

Answer: The number of moles in 200 milliliters =10

The weight of 10 moles of glucose= 1800 grams =1.8 kg

Explanation:

Given: The number of moles in 100 milliliters =5

⇒ The number of moles in 1 milliliters =
`(5)/(100)`

⇒The number of moles in 200 milliliters =
`(5)/(100)*200`

⇒The number of moles in 200 milliliters =10

Also, each mole of glucose weighs 180 grams .

Now, the weight of 10 moles of glucose=
`10*180\ grams`

⇒ The weight of 10 moles of glucose= 1800 grams =1.8 kg
