How is a mixture of water and sugar separated

The easiest way to separate a mixture

of sugar and water is to use distillation,

a process that separates substances

based on their different boiling points.

Sugar does not boil, but the point

at which it crystallizes (320 degrees

Fahrenheit) is much higher than the

boiling point of water (212 degrees

Fahrenheit), so when you boil a mixture

of sugar and water, the water turns to

steam and leaves the sugar behind.

You can collect the steam to capture

the water, effectively separating the

sugar and water. If you are keen to learn

more about distillation, evaporation and

crystallization, this process, involves all

three.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
