Hello! :)
I think you are supposed to record the masses but if it’s asking for the total then add all the triple masses that are given: a. 60g, b. 200g, and c. 3.5g.
Added: 263.5g total.
Answer: 263.5g.
On the other hand, if it is asking for each separate measure on the triple beam balance diagram, the write out the three separate grams:
Answer: a. 60g, b. 200g, and c. 3.5g.
Hope this helped and I hope I answered in time!
Have fun and good luck!
