720 mL
Explanation:
To answer this problem we'll use the <em>definition of molarity</em>:
- Molarity = moles / liters
With that in mind we can <u>calculate the volume in liters</u>:
- 0.25 M = 0.18 moles / liters
Finally we<u> convert liters to mL</u>:
Thus 720 mL of 0.25 M NaOH would have 0.18 moles of NaOH.
Answer:
Therefore, none of the zeros is a significant figure and hence there is only one significant figure in this measurement in support G. The measurement is 0.7 minutes. Here again, zero is not a significant figure and therefore the only significant figure is one which is seven in support Edge.
