Question

t points A 2.80 kg steel gas can holds 15.0 L of gasoline when Full. What is the average density (in kg/m2) of the full gas can, taking into account the volume occupied by steel as well as by gasoline? kg/m Addtional Materials Readng

Answer 1

Give Data

mass of steel can = m_c = 2.80 kg

Volume of gasoline = V_g = 15 L = 0.015 m³

density of gasoline = $\rho$_g = 680 kg/m³

Total mass of gasoline and can = m = m_c + $\rho$_g V_g = 2.80 + 680 x 0.015 =13 kg

density of steel , $\rho$_s = 7600 kg/m³

Volume of steel can = V_s = mass of can / $\rho$_s = 2.8/ 7600 = 0.000368 m³

Total Volume = V_s + Volume of can = 0.000368 + 0.015 = 0.0154

total density = total mass / total volume = 13/ 0.0154 = 844.15 kg/m3
