Several things would be heavier.
Assuming we have the same number of molecules for comparison, per say a mole, or 6.022 x 1023 molecules of a substance, then water would weigh 18.016 g/mol
Knowing the chemical formula of other substances, you could compare, and thus find out whether it is heavier than water.
The answer for this question is that the 300 kilogram because it ways more than the 3 kilometer your welcome
Six pounds is less than 3kg. Six pounds is about 2.72kg

3kg rock = 3000 g rock; so it is heavier because it weighs more. hoping kids use this!
3kg
Six pounds is less than 3kg. Six pounds is about 2.72kg
3kg is equal to 3000 grams.
3kg - 400g is equal to 2.6kg.
3kg 90g is equivalent to 3090g.
3kg is equivalent to 6.6 pounds.
3000mg 250cg 3kg
There are 6 units of 500g in 3kg. This can be calculated by dividing 3000g (3kg) by 500g, which equals 6.
The kilogram (kg) is the SI unit for mass. So an object that is 3kg, has a mass of 3kg.
3kg 740g is equivalent to 3,740 grams.
