You need to work in consistent units. Note that the weight of the bottle is given in grams
and the combined weight of the bottle and water is given in kilograms. Convert the weight
of the combined water & bottle from kilograms to grams. Do this by multiplying 1000 times
the weight in kilograms to find that the combination weighs:
.
1.22 kg * 1000 = 1220 grams
.
Next you can subtract the weight of the bottle (115 grams) from the weight of the bottle-water
combination to find the weight of only the water as follows:
.
Weight of Water = 1220 gms - 115 gms = 1105 gms
.
And since each gram is 1 ml of water, there must be 1105 ml of water.
.
Hope this helps you to see your way through this problem.
