Question

To make a 4.00 M solution, how many moles of solute will be needed if 12.0 liters of solution are required?
A: 6 mol
B: 12 mol
C: 48 mol
D: 120 mol

Answer 1

Answer:

C

Explanation:

Molarity=number of moles/volume

Hence:

Moles required=Molarity×volume

=4mol/L×12L=48moles

Hint:As L(litre will cancel out))

Answer is C

Answer 2

The required moles of solute will be "48 mol".

Molar solution

An aqueous solution containing one mole of something like a chemical dissolved throughout one liter of water or liquid is considered a Molar solution.

According to the question,

Molarity = 4 M

Volume = 12 L

We know the formula,

→ Molarity = $\frac{Number \ of \ moles}{Volume}$

or,

→ Moles required = Molarity × Volume

By substituting the values, we het

                             = 4 × 12

                             = 48 moles

Thus the correct answer be "Option C" i.e., 48 mol.
