Final answer:
The volume of a 0.521 gram sample of air, with a density of 1.09 g/L, is approximately 0.478 L.
Step-by-step explanation:
To find the volume of a sample of air, we can use the formula:
Volume = Mass / Density
In this case, the mass of the air sample is 0.521 grams and the density of air is 1.09 g/L.
Let's plug these values into the formula:
Volume = 0.521 g / 1.09 g/L
After dividing, we get a volume of approximately 0.478 L.
