Answer:
To calculate the mass of gasoline, we need to multiply the volume of gasoline by its density. Given that the density of isooctane is 0.692 g/ml, we can use this value to calculate the mass.
Mass = Volume × Density
Given:
Volume = 220 ml
Density = 0.692 g/ml
Mass = 220 ml × 0.692 g/ml
Mass = 152.24 g
Therefore, the mass of 220 ml of gasoline is 152.24 grams.
