Answer:
The volume of a 0.200 M KCl solution containing 5.00 10-2 mol of solute is 0,25 L
Explanation:
Molarity (M) means: moles of solute which are contained in 1 L of solution.
In this case we have 0,2 moles which are in 1 L, so, as we have 5x10*-2 moles we have to apply a rule of three to find out the volume.
0,2 moles ........... 1 L
5x10*-2 moles ........... x
x= (5x10*-2 moles . 1 L) / 0,2 moles = 0.25L
(we can also say 250 mL)

Testable, that is always required for a hypothesis. Otherwise, how can you prove it?
The origins of the word fossil are French and Latin
Energy levels inside an are the specific that electrons can have when occupying specific orbitals. Electrons can be excited to higher by absorbing from the surroundings. Light is emitted when an electron relaxes from a high state to a lower one.
