Question

How many moles of glucose are present in 1.0 liters of a 2.5 M solution of glucose water

Answer 1

Moles = ?

Volume = 1.0 L

Molarity = 2.5 M

moles = M x V

moles = 2.5 x 1.0

= 2.5 moles of glucose

Answer 2

Moles of glucose = 2.5 moles

Step-by-step explanation:

Given:

Volume of the glucose solution, V = 1.0 L

Concentration or molarity of the solution = 2.5 M

To determine:

The number of moles of glucose in the above solution

Step-by-step explanation:

Concentration of a given solution can be expressed in terms of Molarity which denotes the number of moles of a solute present in a liter volume of a solvent

`Molarity = (moles\ of \ solute)/(Liter\ of\ solvent)`

`moles\ of\ solute = Molarity*Volume`

In this case,

`moles\ of\ glucose = 2.5\ moles/L* 1.0 L = 2.5\ moles`
