Question seems to be incomplete without density of gasoline and steel. Assuming density of gasoline to be 0.8 kg/lit and of steel to be 7.8kg, total weight=2.6+(15x0.8)=14.6 kg
Total vol=2.6/7.8+15=0.33+15=15.33 lit
Av density=14.6/15.33=0.95 kg/lit
A 2.60 kg steel gas can holds 15.0 L of gasoline when full. What is the average density of the full gas can, taking into account the volume occupied by steel as well as by gasoline?
