a 15-gram sample of a gas has a volume of 30 liters at standard pressure. what is the densty of the gas
density=mass/volume
To find the density of the gas, we need to determine the mass divided by the volume.
The given mass of the gas is 15 grams. Since the density is typically expressed in units of grams per liter (g/L), we have the mass in the correct unit.
The volume of the gas is 30 liters.
Now we can calculate the density:
Density = Mass / Volume
Density = 15 grams / 30 liters
Density = 0.5 g/L
Therefore, the density of the gas is 0.5 grams per liter.
