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?

Respuesta :

Answer:  The number of moles in 200 milliliters =10

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


Step-by-step explanation:

Given: The number of moles in 100 milliliters =5

⇒ The number of moles in 1 milliliters =[tex]\frac{5}{100}[/tex]

⇒The number of moles in 200 milliliters =[tex]\frac{5}{100}\times200[/tex]

⇒The number of moles in 200 milliliters =10

Also, each mole of glucose weighs 180 grams .

Now, the weight of 10 moles of glucose= [tex]10\times180\ grams[/tex]

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