Question

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

Answer 1

Answer: 0.4375 mols of solute

Step-by-step 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=(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=(x)/(1.75L)` [multiply both sides by 1.75 L]

`x=0.4375 mols`

There are 0.4375 mols of solute.
