Weight of Gasoline

The volume of the gasoline bottle is 15 liters. What is the weight of an entire bottle of petrol if the empty one weighs 1 kg? The density of gasoline is approximately 730 kg/m³.

Final Answer:

m₂ =  11.95 kg

Step-by-step explanation:

$$\begin{gathered} V=15\text{l}\to {\text{m}}^3=15:1000{\text{m}}^3=0.015{\text{m}}^3 \\ {m}_0=1\text{kg} \\ \rho =730{\text{kg/m}}^3 \\ {m}_1=\rho \cdot V=730\cdot 0.015=\frac{219}{20}=10.95\text{kg} \\ {m}_2=m_0+m_1=1+10.95=11.95\text{kg} \end{gathered}$$
