Filtration is used to separate different particles, so it is based on the particle size.

Filtration can be used to separate mixtures based on the size of their particle.

Filtration is a method to separate different molecule based on size. Filtration mostly used to separate solid substance in a liquid. To separate the molecule, you will need a tools that have smaller holes than the molecule size.
The example of usage of this method would be when you try to remove a substance from homogeneous solution using filter paper. The size of water molecule will be smaller than the paper so the water can pass through. But if the solute size is larger than the paper pore, it will be held and form a residue.

Sliva [168]

Answer:

6.1

Explanation:

Because if you get to the large mark it would be 5 but since its not at 5, it would be 6.1 as you can see in my drawing. It aligns perfectly with 6.1.

What is the freezing point in °C) of a 0.195 m

Elina [12.6K]

Answer:

$T_S=-1.09\°C$

Explanation:

Hello!

In this case, since the freezing point depression for a solution is computed via:

$(T_S-T_W)=-imK_f$

Whereas TW is the freezing temperature of water, TS that of the solution, i the van't Hoff's factor (3 for K2S as it ionizes properly), m the molality of the solution and Kf the freezing point constant of water. Thus, we plug in to obtain:

$(T_S-0\°C)=-3*0.195m*1.86\frac{\°C}{m}\\\\T_S=-1.09\°C$
