<u>Answer:</u> The molarity of solution is 0.954 M
<u>Explanation:</u>
We are given:
5.098 mass % solution of potassium hydroxide
This means that 5.098 grams of potassium hydroxide is present in 100 grams of solution
To calculate volume of a substance, we use the equation:
Density of solution = 1.05 g/mL
Mass of solution = 100 g
Putting values in above equation, we get:
To calculate the molarity of solution, we use the equation:
Given mass of potassium hydroxide = 5.098 g
Molar mass of potassium hydroxide = 56.1 g/mol
Volume of solution = 95.24 mL
Putting values in above equation, we get:
Hence, the molarity of solution is 0.954 M
Answer:
=> 0.10 moles
Explanation:
The question is asking us to find the moles of NaCl cid formed.
We have been provided with;
0.10 L of 1.0 M NaOH.
We know that mole ratio of the reaction is 1:1 and also the molarity of a solution is contained in 1 L or 1000 mL or 1000 cm³.
This means that;
1.0 M is contained in 1.0 L.
X mol is contained in 0.10 L
= 0.10 moles of NaCl formed
