Question

What is the molarity of a 750.0 milliliter solution containing 2.5 moles of solute?

Answer 1

The molarity of a solution equals to the mole number of the solute divided by the volume of the solution. So the molarity is 2.5/0.75=3.33 mol/L.

Answer 2

Answer: 3.33M

Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

$Molarity=\frac{n\times 1000}{V_s}$

where,

n = moles of solute = 2.5 moles

$V_s$ = volume of solution in ml= 750 ml

Now put all the given values in the formula of molarity, we get

$Molarity=\frac{2.5moles\times 1000}{750ml}=3.33M$

Therefore, the molarity of solution is 3.33 M.
