A 2.00 kg steel gas can holds 25.0 L of gasoline when full. What is the average density (in kg/m3) of the full gas can, taking into account the volume occupied by steel as well as by gasoline?

Answer:80kg/m^3

Explanation:

1L = 0.001m^3

25L= 25 *0.001 = 0.025m^3

Average density =mass/volume

Average density =2/0.025=80kg/m^3

Answer:

density= 750 kg/m³

Explanation:

Given Data

[tex]V_{gas}=25L\\ m_{can}=2.00 kg\\ P_{gas}=6.7*10^{2} kg/m^{3}\\   density=?[/tex]

Solution

[tex]P=m/v\\P_{gas}=m_{gas}/V_{gas}\\ m_{gas}=P_{gas}V_{gas}\\m_{gas}=(6.7*10^{2} )(25*10^{-3} )\\m_{gas}=16.75 kg\\P_{sys}=(m_{gas}+m_{can})/V_{sys}\\P_{sys}=(16.75+2)/25*10^{-3}\\ P_{sys}=750 kg/m^{3}[/tex]
