Answer:
mass in a given volume
Explanation:
Density is the mass in a given volume or mass per unit volume of a substance.
Mass is defined by the amount of matter present in a substance.
Volume is the space occupied by a body.
- Density is the mass divided by the volume
Mathematically;
Density = 
78.4 L volume of container is required to hold 3.2 moles of gas.
Explanation:
- STP is defined as the standard temperature and pressure of a gas in room temperature conditions. At STP, one mole of the gas which has Avogadro's number of molecules in it will occupy a volume of 22.4 L.
- So, one mole of a substance or gas will occupy a volume of 22.4 L then the volume of the container needed for 3.2 moles of gas is calculated by multiplying 22.4 L, standard volume with the moles of the gas 3.2 moles.
- Hence, the answer would be 78.4 L.
