Answer:
6.69 moles
Explanation:
Data obtained from the question include:
Volume = 2230mL
Molarity of NaOH = 3 M
First, we'll convert 2230mL to L. This is illustrated below:
1000mL = 1L
2230mL = 2230/1000 = 2.23L
Now, we can obtain the number of mole of NaOH in the solution as follow:
Molarity = mole /Volume
Mole = Molarity x Volume
Mole of NaOH = 3 x 2.23
Mole of NaOH = 6.69 moles
Therefore, the total number of mole of the solute (NaOH) in the solution is 6.69 moles
