Is 8456 g greater than 9 liters?

Answer 1

If the substance has a density less than approx 939.56 g/l = 0.93956 g/cm³ then a MASS of 8456g of the substance will have a VOLUME greater than 9 liters.

---------------------------

What you have asked is a nonsense question since

• grams are a measure of mass, whereas
• liters are a measure of volume.

The two are connected by the density of the substance making up the mass/volume.

IF you meant "Is 8456 ml greater than 9 liters" then:

Convert the units to the same measure (of volume) and the comparison can be made:

The mili- prefix means 1/1000 → 1 ml = 1/1000 l

→ 8456 ml = 8456 × 1/1000 l = 8.456 l

8.456 < 9 → 8.456 l < 9 l → 8456 ml < 9 l

→ No, 8456 ml is greater than 9 liters.

Answer 2

There can be no comparison. A gram is a measure of mass. A litre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. Consider a litre of air. How many grams? Next consider the same volume of water. How many grams? The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
