Hi!

You calculated the correct amount of final volume which is 1.5L but the question is asking the amount of water needed to be added so, in order to find that you have to subtract initial volume from final volume.

Vf-Vi=1.5L-0.5L=1.0L

Hope it makes sense:)

oh!! thank you so much i was so confused, I guess I have to sleep now hahaha
