Answer:
0.375mol/L
Explanation:
Well you were given the mole of solute (n) =0.133 and the volume of solvent (V) =355mL
Note that the molar Conc. also called Molarity = (n) the mole of solute/ (V) the volume of solvent
But keep in mind that the volume should always be in liter (L). Therefore, convert mL to L by dividing 1000:
V= 355mL/1000 = 0.355L
In the end, we apply the formula:
M = n/V
M= 0.133/0.355 = 0.3746mol/L ≈ 0.375mol/L
Taking into account the definition of molarity, the molar concentration of sucrose in the beverage is 0.375 [tex]\frac{moles}{liter}[/tex] .
Molar concentration is a measure of the concentration of a solute in a solution, whether it is some molecular, ionic or atomic species. So, molarity indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution, as follows in the expression:
[tex]molarity=\frac{amount of moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
In this case, you know:
- amount of moles of solute= 0.133 moles
- volume= 355 mL= 0.355 L (being 1000 mL= 1 L)
Replacing in the definition of molarity:
[tex]molarity=\frac{0.133 moles}{0.355 L}[/tex]
Solving:
molarity= 0.375[tex]\frac{moles}{liter}[/tex]
Finally, the molar concentration of sucrose in the beverage is 0.375 [tex]\frac{moles}{liter}[/tex] .
