<u>Answer:</u> The initial molarity of cation is 2.38 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Given mass of 
= 46.3 g
Molar mass of = 129.6 g/mol
Volume of solution = 150 mL
Putting values in above equation, we get:
1 mole of produces 1 mole of 
cation and 1 mole of 
anion
So, molarity of cation = (1 × 2.38) = 2.38 M
Hence, the initial molarity of cation is 2.38 M
The best method for separating two liquids in a mixture is distillation among the choices. Distillation separates liquids in terms of their volatility. Evaporation separates liquid from solid. This also applies for filtration which applies porous media for separation. Sorting is applied for two or more different kinds of solids. Answer is distillation.
Al2S3. Al has a +3 charge and S has a -2 charge, generally speaking
In preparing diluted solutions from concentrated solutions we can use the following formula
c1v1 = c2v2
c1 and v1 are the concentration and volume of the concentrated solution respectively
c2 and v2 are the concentrations and volume of the diluted solution respectively
Substituting these values ,
20 mL x 1.0 M = C x 60 mL
C = 0.33 M
The concentration of the resulting diluted solutions is 0.33 M
