Well, I gets a 3*"mole"3mole quantity of KClKCl.......

Explanation:

"Molarity"="Moles of solute"/"Volume of solution"Molarity=Moles of soluteVolume of solution.........

And thus for "moles of solute"moles of solute, we take the product,

"Molarity"xx"Volume of solution"Molarity×Volume of solution

=3*mol*cancel(L^-1)xx1000*cancel(mL)xx10^-3*cancelL*cancel(mL^-1)

=3.0*mol

Given that "Avogadro's number"-=6.022xx10^23*mol^-1, how many ATOMS are in this quantity?
