Answer:
Sodium Hydroxide
Please mark me as brainlest because I have help you pleaseeeee.
Explanation:
Sodium hydroxide is a common proton acceptor also known as lye. It is the active ingredient in oven cleaners and drain cleaners because it can react with fats to produce compounds that dissolve in water. It is also used in many school laboratories to demonstrate acid-base reactions.
Answer : The concentration of solution is, 8.53 M.
Explanation :
As we are given, 45.0 mass % solution of ethanol in water that means 45.0 g of ethanol present in 100 g of solution.
First we have to calculate the volume of solution.


Now we have to calculate the molarity of solution.
Mass of
= 45.0 g
Volume of solution = 114.5 mL
Molar mass of
= 46.07 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :

Now put all the given values in this formula, we get:

Therefore, the concentration of solution is, 8.53 M.
