You are watching: What is the molarity of a solution containing 0.325 moles of solute in 250 ml of solution?

1.0 mol/dm3

Explanation:

Given that:

Amount of mole = 0.25 moles

Volume = 250 millliters that solution

Convert milliliters come liters

If 1000 milliliters = 1 liter

250 milliliters = (250/1000) = 0.25 L

Recall the 1 liter = 1dm3

so, 0.25 liters = 0.25 dm3

Now, molarity is calculated by dividing the quantity of a substance by the volume the the solution.

i.e Molarity = (Amount in moles/volume in dm3)

Molarity = (0.25 mole / 0.25 dm3)

= 1.0 mol/dm3

Thus, the molarity of the systems is 1.0 mol/dm3

1/3 M

Explanation:

Molarity is characterized as moles every liter:

(0.25 moles)/(0.75 liters) = 1/3 moles/liter = 1/3 M

Molarity have the right to be characterized as the variety of moles that solute in 1 together of solution.M = n/VWhere M is the molarity the the equipment (M or mol/L), n is the moles of the solute (mol) and V is the volume that the solution (L).Here, solute is KF.n = 0.250 molV = 0.500 LM = ?By applying the formula, M = 0.250 mol / 0.500 together M = 0.500 mol/LHence, the molarity that KF equipment is 0.500 mol/L.
