Question

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 1

Answer:80kg/m^3

Step-by-step 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 2

density= 750 kg/m³

Step-by-step explanation:

Given Data

`V_(gas)=25L\\ m_(can)=2.00 kg\\ P_(gas)=6.7*10^(2) kg/m^(3)\\   density=?`

Solution

`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)`
