Answer:
What is the molarity of a solution containing 5.00 moles of kcl in 2.00L of solution? Molarity= moles of solute/volume of solution in litre , so the problem looks like this : 7/. 569 , which is equivalent to 12.302 M .
Answer:
The solid particles will be trapped behind on the strainer while the liquid molecules will pass or filter through.
Explanation:
Filtration is a process of separation of mixtures involving an insoluble solid and a fluid such as liquids or gases using a filtering medium such as paper or cloth or any other material. During the process, the liquid molecules pass through the filtering medium whereas the solid particles are not allowed to pass through but are retained by the medium. The reason is that the pores on the filtering medium are only small enough for the liquid molecules to pass through but not the solid particles.
An example of a mixture that can be separated through filtration is a suspension of chalk and water. Also, a mixture of water and solid particles such as water and tea leaves can also be separated using a strainer with cloth.
In the question, if a mixture of insoluble solids in a liquid is passed through a strainer with cloth, the solid particles will be trapped behind on the strainer while the liquid molecules will pass through.
Molar mass (formula, molecular mass) is the mass of one mole of a chemical element or a chemical compound. Molar mass is suitable and often used in chemistry because it allows for a light conversion between stoichiometric (molar) relationships represented by a chemical equation and mass relations, which are more significant in practice.
The molar mass of a compound is obtained by the sum of the atomic weights of the atoms which form a compound.
So, formula mass of P4 is:
M(P4) = 4 x Ar(P) = 4 x 31 = 124 g/mole
