Question

How many grams of glucose would you use to make 200ml of a 1m sugar solution

Answer 1

Mass of glucose will be 36 gram

Explanation:

We have given volume of solution V = 200 ml =0.2 L

Morality = 1 M

Molar mass of glucose = 180 g/mol

We know that morality is given by

`molarity=(number\ of\ moles)/(volume\ of\ solution\ in\ liters)`

`1=(number\ of\ moles)/(0.2)`

`number\ of\ moles\ n =0.2`

We know that number of moles is given by

`n=(mass\ in\ gram)/(molar\ mass)`

`0.2=(mass\ in\ gram)/(180)`

Mass = 36 gram
