Answer:
The amount of water in a 95 mL sample of the solution is 33.25 mL
Explanation:
65% (v/v) rubbing alcohol is a solution containing 65 mL rubbing alcohol in 100 mL solution of the rubbing alcohol and water
Therefore, 95 mL sample of the solution will contain x mL of rubbing alcohol;
x = 65% × 95 = 0.65 × 95 = 61.75 mL rubbing alcohol and therefore, the amount of water contained = 95 - 61.75 = 33.25 mL
The amount of water in a 95 mL sample of the solution = 33.25 mL.
<u>Answer:</u> The volume of stock solution of ammonia that is needed is 48.67 mL
<u>Explanation:</u>
To calculate the volume of stock solution, we use the equation:
where,
are the molarity and volume of the stock ammonia solution
are the molarity and volume of diluted ammonia solution
We are given:
Putting values in above equation, we get:
Hence, the volume of stock solution of ammonia that is needed is 48.67 mL
