Question

Will mark brainliest :) how many moles of a solute is present in 4.00 L of an 8.30 M solution?

Answer 1

The answer is 33.2 moles of a solute is present in 4.00 L of an 8.30 M solution , Option A is correct .

What is Molarity ?

Molarity is defined as the amount of solute (in moles)in per litre of solution.

It is also known as molar concentration of a solution , It is expressed in mol/l

$\rm M =\dfrac{moles \;of\; solute}{Volume \;of \;solution} \\\\\\\rm M = \dfrac{n}{V}$

We can rearrange this equation to get the number of moles:

n= M * V

The molarity of solution is 8.3 M and the volume given is 4 litres

the moles will be n = 8.30 * 4 = 33.2 moles

Therefore 33.2 moles of a solute is present in 4.00 L of an 8.30 M solution , Option A is correct .
