Density can be defined as the mass of a sample present per unit volume.
![Density = \frac{Mass}{Volume}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7BMass%7D%7BVolume%7D)
Given the volume of air = 125 mL
Converting air from mL to L,
![125 mL * \frac{1 L}{1000 mL} = 0.125 L](https://tex.z-dn.net/?f=125%20mL%20%2A%20%5Cfrac%7B1%20L%7D%7B1000%20mL%7D%20%3D%200.125%20L)
Density of air = 1.197 g/L
Calculating the mass of air from density and volume:
Mass of air = ![0.125 L * \frac{1.197g}{L} =0.150 g](https://tex.z-dn.net/?f=0.125%20L%20%2A%20%5Cfrac%7B1.197g%7D%7BL%7D%20%3D0.150%20g)
Therefore, the mass of 125 mL of air with a density of 1.197 g/L is <u>0.150 g</u>
Given:
T1 = 300 K
P1 = 500 kPa
P2 = 100 kPa
T2 = ?
Assume that the gas inside the container behaves ideally, we can use the ideal gas equation.
Additional assumption, volume remains constant.
PV = nRT
P/T = nR/V = constant
P1/T1 = P2/T2
500 kPa / 300 K = 100 kPa / T2
T2 = 60 K
