Answer:
Molarity = 0.3 M
Explanation:
Given data:
Moles of NaOH = 0.720 mol
Volume of water = 2.40 L
Molarity = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Molarity = 0.720 mol / 2.40 L
Molarity = 0.3 mol/L
Molarity = 0.3 M
Answer:
<h3>The answer is 1.63 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula

From the question
actual mass = 9.80 g
error = 9.80 - 9.64 = 0.16
We have

We have the final answer as
<h3>1.63 %</h3>
