Question

What's the amount of solute in 1.75 L of 0.25 M HCl?

Answer 1

Answer: 0.4375 mols of solute

Explanation:

The problem is asking for the amount of solute. We are given the value of molarity. The molarity is 0.25M. We know that molarity is $M=\frac{mols of solute}{liters of solution}$. Since we are given the liters of solution is 1.75, we can use those values to solve for mols of solute.

$0.25M=\frac{x}{1.75L}$                        [multiply both sides by 1.75 L]

$x=0.4375 mols$

There are 0.4375 mols of solute.
