How many ml of water will it take to fill 2.0 l bottle that already contains 1.25 l of

First off, we can find the volume that need to be filled:

2-1.25

=0.75L

Asbthe unit is still in Litres,we need to converge it to mL.

1L = 1000mL

mL needed:

=0.75×1000

=750mL

Therefore the answer is 750mL.

Hope it helps!
