Answer:
The conventional oven and the convection oven are confused with each other due to their similar look and style, and a lot of their functioning is quite the same as well.
The conventional ovens have existed for over half a century, and have derived their functioning from traditional ovens that are over 4,000 years. They function with a bottom-up heat transfer from a fixed burner source.
The convection ovens were made recently as a way to get better heating results for all types of dishes and recipes, with the introduction of a fan system along with an exhaust which allows the circulation of hot air around the cavity of the oven.
Explanation:
Remember the equation for molarity:
![molarity = \frac{moles}{volume}](https://tex.z-dn.net/?f=molarity%20%3D%20%20%5Cfrac%7Bmoles%7D%7Bvolume%7D%20)
*note that volume is in liters*
They give you grams (14.3 g), which can give you moles if you divide it by the molar mass of LiCl (about 42.4 g/mole).
14.3g/42.4= 0.34 moles
They also give you volume, already in liters:
0.45L
Now, it's a "plug and chug" question.
![molarity = \frac{0.34moles}{0.45liters}](https://tex.z-dn.net/?f=molarity%20%3D%20%20%5Cfrac%7B0.34moles%7D%7B0.45liters%7D%20)
Then, you should get your answer.
Hope that helps!
