Mole calculation

If you add 10.0 mL of 1.9 M NaOH, how many moles of NaOH would that be? You will need to calculate it using n = cv. Report your figure to two decimal places.

(If you are struggling with some of the maths in Chemistry there is a lot of help. See the maths hub on Moodle and talk to you TA or unit coordinator to find support.)

Mass calculation

Assuming you had 0.013 moles of copper chloride, what amount of 4 M NaOH would be the minimum volume you could use in Section 2.1 of Exercise 3?

State your answer in millilitres but remember SI units are litres. Report to one decimal place. Do not include units with your answer.
