Is 100g equals l liters

Answer 1

It is non sense to (directly) compare units of mass (grams) and units of volume (liters).

However, they are related by density:

density = mass/volume

Thus if a substance has a density of 100 g / 1 liter = 100g / 1000 cm³ = 0.1 g/cm³ then 100g of it will occupy a volume of 1 liter.

Answer 2

You can't compare grams (a unit of mass) to liters (a unit of volume), unless you also specify a specific substance.
