Question

If 0.5 moles of CaO is mixed into 2 liters of solution, what is the molarity? Group of answer choices 0.25 moles / liter 4 moles / liter 0.5 moles / liter 2 moles / liter

Answer 1

The correct answer is 0.25 moles/liter

Step-by-step explanation:

Molarity is a measure of concentration and is defined as the moles of solute in 1 liter of solution.

2 L solution-----0,5 moles of CaO

1 L solution -----x= (1 L solutionx0,5 moles of CaO)/2 L solution =

x=0, 25 moles of Cao ---> 0,25M
