A celendric can with a bottom area of 1.2 dm2 and a height of 20 cm

A celindrical can with a bottom area of 1.2 dm2 and a height of 20 cm is half filled with gasoline, the mass of gasoline in a can is 0.85 kg, determine the density of gasoline.

Initial data: S (bottom area of a cylindrical can) = 1.2 dm2 (1.2 * 10-2 m2); h (can height) = 20 cm (0.2 m); h1 (level of gasoline in the bank) = 0.5h; m (mass of gasoline in a can) = 0.85 kg.

1) The volume of gasoline in a cylindrical can: V = S * h1 = S * 0.5h = 1.2 * 10-2 * 0.5 * 0.2 = 0.0012 m3.

2) Let’s calculate the density of gasoline: ρ = m / V = 0.85 / 0.0012 = 708.3 kg / m3.

Answer: The estimated density of gasoline is 708.3 kg / m3.
