Answer: There are 0.006 moles of acid in the flask.
Explanation:
Given: = 21.35 mL,
= 0.150 M
= 25.0 mL,
= ?
Formula used to calculate molarity of is as follows.
Substitute the values into above formula as follows.
As molarity is the number of moles of a substance present in a liter of solution.
Total volume of solution =
= 21.35 mL + 25.0 mL
= 46.36 mL (1 mL = 0.001 L)
= 0.04636 L
Therefore, moles of acid required are calculated as follows.
Thus, we can conclude that there are 0.006 moles of acid in the flask.
