Question

0.500 mile of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (plz help!) plz no links

Answer 1

The correct question is as follows: 0.500 moles of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (plz help!)

Answer: The molarity of this solution is 0.25 M.

Step-by-step explanation:

Molarity is the number of moles of a substance divided by volume in liter.

As it is given that there are 0.5 moles of potassium oxide in 2.00 L of water so, the molarity of this solution is calculated as follows.

`Molarity = (moles)/(volume(in L))\\= (0.5 moles)/(2.00 L)\\= 0.25 M`

Thus, we can conclude that molarity of this solution is 0.25 M.
