D , is the correct answer
4. Snow removal, as its snows a lot in Pennsylvania.
5. For number 5 please tell me which services the company offers & keep in mind the weather patterns are pretty hot & sunny in Florida, especially during the summers. If the company provides services (such as snow removal) Florida would hardly need any, causing the company to make less profit.
Good luck & please be sure to try your best. You got this!
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
.
<h3>Definition of molarity</h3>
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
.
<h3>This case</h3>
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
.
