Question

If you had 0.5 M KCl solution, how many moles of solute would you have in 1 Liter of solution?

the answer I got it 0.5 moles? Is this right?

Answer 1

I agree with you....

Explanation:

...there are `1/2*mol` potassium ions, and `1/2*mol` chloride ions.

And remember the definition of concentration...

`"concentration"="moles of solute"/"volume of solution"`

And so the product...

`"concentration"xx"volume of solution"="moles of solute"`

And here we got the product...

`0.5*mol*cancel(L^-1)xx1*cancelL=0.50*mol`...and answer in moles are required...
