Question

water is than petrol in weight​

Answer 1

Step-by-step explanation:

Because water molecules are small and pack tightly together, causing water to have a greater density than petrol. Density relates to the mass per unit volume. If your molecules are heavier but take up more space, the net result could be more or less mass per unit volume

Answer 2

Answer:

Water is heavier

Step-by-step explanation:

water has density ~1 g/cm³ whilst petrol has ~0.8-0.9 g/cm³, so petrol is lighter than water
