Explanation:
Molarity is a measure of concentration in moles per liter.
There are 0.250 moles of sodium hydroxide (NaOH) and 500 milliliters of water. We need to convert milliliters to liters. Remember that 1 liter contains 1000 milliliters.
Now we have the values to solve for molarity:
- moles= 0.250 mol NaOH
- liters= 0.5 L
Substitute the values into the formula.
Divide.
- 1 mole per liter (mol/liter) is equal to 1 Molar or M.
- Our answer of 0.5 moles of sodium hydroxide per liter is equal to 0.5 M NaOH
The molarity of the solution is <u>0.5 M NaOH</u>
