The rule that we will use to solve this problem is:
M1V1 + M2V2 + M3V3 = MtVt
where:
M1 is the molarity of first solution = 0.003 molar
V1 is the volume of the first solution which is the X that we want to find
M2 is the molarity of second solution = 0.0001 molar
V2 is the volume of second solution = 20 ml
M3 is the molarity of third solution = 0.002 molar
V3 is the volume of the third solution = 30 ml
Mt is the final total molarity = 0.0015 molar
Vt is the final volume = V1+V2+V3 = X+20+30 = (X+50) ml
Substitute with the above givens in the equation to get X as follows:
0.003X + 0.0001(20) + 0.002(30) = (X+50)(0.0015)
0.003X + 0.062 = 0.0015X + 0.075
0.003X - 0.0015X = 0.075 - 0.062
0.0015X = 0.013
X = 0.013 / 0.0015
X = 8.667 ml
Answer:
C) The mass will double.
Explanation:
The amount of solute that will dissolve will also double since the solvent volume has doubled.
There is a fine liner relationship between amount of solute and solvent that can form a solution.
- A solute is the substance that is dissolved in another.
- A solvent is the medium by which a solute is dissolved.
- A combination of solute and solvent forms a mixture called solution.
To form a solution, solvation must take place. During solvation, the molecules of the solvent surrounds the solute completely and bring them into the phase of dissolution.
Generally, the more the solvent, the more the solute it is able to dissolve.
A table spoon of sugar for example will dissolve readily in a jar of water without settling. In a bucket, it is even much more easier.
Answer : The correct option is, (B) bimolecular
Explanation :
Molecularity : It is defined as the total number of reactant molecules taking part in the balanced equation of a reaction. It is a theoretical concept.
The given balanced chemical reaction is,
The number of reactants molecules taking part in the balanced equation of a reaction are, and .
In this reaction, 1 molecules reacts with the 1 molecule.
Total number of reactant molecule = 1 + 1 = 2
The molecularity of the reaction is 2 that means, the elementary reaction is bimolecular.
Hence, the correct option is, (B) bimolecular
