You are talking about voulme - 19 litres... if u want to know the mass- kilograms u must have density. because
density = mass/volume. - (point 1)
now density of water is not a fixed quantity. it varies as temperature changes.. it is at its maximum at around 4 degrees centigrade.. (point 2)
So there can not be a general answer to your question..(point 3)
if you want a precise answer u should provide temperature also.. but roughly taking the density to be 1kg/litre, the mass of 19 litre water can be taken to be 19 kg.

The definition of 1 Kg is the weight of 1 L of pure water. So, 19 litres = 19 Kg (if the water is pure)

When I went to school many years ago, we were taught that at four degrees one cubic centimetre of water was one gramme. This would mean that 19 litres, or 19000 cubic centimetres, would weigh 19 kilogrammes.

if you're talking about "kilos", i think you mean "kilogramms". so, if you take water at a temperature of 4°C, where it has its highest density, the answer would be: 19 kilogramms

About 18.989 kg
1 gallon of water weighs 8.34lbs.
1 gallon is 3.785liters.
19 liters is about 5.02 gallons.
19 liters is about 41.865 lbs.
41.865 lbs is about 18.989 kg.
