Given the eqaution c=n/v, where:
c = concentration
n = number of moles
v = volume
so, n=cv, that is: n = .25 X .4
= 0.1 mol
To find out the number of moles is to compute for the molarity of the solution. First divide moles of solute by 250 ml the answer will be 0. 25 ml then multiply it by 0. 4m solution youâ??ll get 0. 1 mol as the final answer for the number of moles.
You need to get it per litre. 250x4 will give you 1 litre, so 0.325x4 will give you your molarity. This gives a molarity of 1.3 (molar).
Given the eqaution c=n/v, where:
c = concentration
n = number of moles
v = volume
so, n=cv, that is: n = .25 X .4
= 0.1 mol
Molarity = moles of solute/volume of solution
M = 0.25 moles/0.50L = 0.5M
0.325 X 1000/250 = 1.3 molar
It is 0,5 molar.
Molarity = moles of solute/Liters of solution Molarity = 5 moles solute/4.5 Liters of solution = 1 M solution ==========
Molarity = moles of solute/Liters of solution Without the solute name the mass ( 8 grams ) does no good. Mass of solute (1 mole/molar mass of solute) = moles solute ----------------------then use Molarity equation. ( remember convert to liters )
Molarity means moles in a litre. Therefore you need to divide by 3.95. 1.4/3.95 is 0.35443 molar.
Increasing the amount of the solute in the solution the molarity and the density of this solution increases.
Molarity = moles of solute/Liters of solution
The molarity of a solution containing 7.0 moles of solute in 569mL of solution is a)81M b)0.081M c)12M D)4.0M The answer is C. 12M 7 x 1000/569 = 12.302
Molarity = moles of solute/Liters of solution Molarity = 5 moles solute/4.5 Liters of solution = 1 M solution ==========
Molarity = moles of solute/Liters of solution Without the solute name the mass ( 8 grams ) does no good. Mass of solute (1 mole/molar mass of solute) = moles solute ----------------------then use Molarity equation. ( remember convert to liters )
Molarity= No. of moles of solute/Volume of solution(in litre) or No. of moles of solute*1000/Volume of solution(in ml)
Molarity means moles in a litre. Therefore you need to divide by 3.95. 1.4/3.95 is 0.35443 molar.
The concentration in moles of a substance in the solution
The number of moles of a solute per kilogram of solvent. (Apex)
Molarity = moles solute/ Liters solution
moles of solute/L of solution
You need to know the moles of solute and the VOLUME of SOLUTION.
Increasing the amount of the solute in the solution the molarity and the density of this solution increases.
Molarity is defined as moles solute/liter of solution.Moles of solute = 2.5 moles sucrose Liters of solution = 0.5 liters Molarity (M) = 2.5 moles/0.5 liters = 5 M
