Density varies on temperature. At near room temp (20 degrees C) the density of water is 0.998 g/ml. Everyone just rounds it to 1, but that really isn't true unless your at about 4 degrees C.

It is a definition, when the metric system was invented the kilogram was defined as the mass of 1 liter of water.
Because it is a definition there is an infinite number of zeros in the number. Significant figures apply only to measurements

1 and 1.000000 are the same number just represented with differing numbers of decimal places.

Because it only is one significant figure. Maybe. But I think it doesnt really matter. I think 1.000000 works too

the density of a substance tends to change with the surrounding conditions. temperature and air pressure can affect how densely the chemical is packed, so setting the density to be that specific is trivial.
