The molar mass of glucose is 180 grams per mole (g/mol). Which of the following procedures should you carry out to make a 1 M so

Strike441 [17]

Answer:

You need to dissolve 144 gr of glucose in 0.8 liters of water to have a 1 M solution.

Explanation:

Molarity is the amount of moles per liter of solution --> moles/liters. We are trying to get a 1 molar solution and we also know the liters (0,8L) so

$1\frac {moles-of-glucose}{liters-of-water} =\frac{X moles-of-glucose}{0.8 liters-of-water} \\$

$1\frac{Moles-of-glucose}{liters-of-water } * 0.8 liters of water$

after canceling liters of water you get 0,8 moles of glucose.

$180 \frac{grams-of-glucose}{mol-of-glucose}*0.8 mol- of- glucose=144 grams-of-glucose$
