Taking into account the definition of molarity, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 .
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units .
In this case, you have:
- number of moles= 30 moles
- volume= 0.80 L
Replacing in the definition of molarity:
Solving:
<u><em>Molarity= 37.5 </em></u><em />
Finally, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 .
