0.8 is the density of an unknown gas in g/l that has a volume of 10.9 l and has a mass of 8.72 g.
What is density?
The mass for each unit volume of a given material is the definition of that material's density. Density, or mass per unit volume, is defined as the ratio of mass to volume. It gauges how much material an object contains in relation to its volume (cubic metre or cubic centimeter). In essence, density is a measurement of how closely together matter is packed.
Mass of the unknown gas = 8.72g
Volume of the gas = 10.9 l
Density of the gas = mass/volume = 8.72/10.9 g/l = 0.8g/l.
Thus, An unidentified gas with a volume of 10.9 l and a mass of 8.72 g has a density of 0.8 in g/l.
