How did you get 20?

Write the equation for the reaction, then find the number of moles of HCl needed. Then find the volume of HCl needed

2017 OCR A A2 paper 1. i searched up the question and found a thread on it and the person asked why it was 20cm cubed when it isnt even that in the MS so i was a bit lost
