Well, there are 0.125*mol with respect to "calcium nitrate"...

Explanation:

By definition...."molarity/concentration"="moles of [solute](https://socratic.org/chemistry/solutions-and-their-behavior/solute)"/"volume of solution"

And so with the given data, we take the product...

"moles of solute = concentration"xx"volume"=0.25*mol*L^-1xx500*mLxx10^-3*L*mL^-1=0.125*mol...

What mass of salt does this represent?
