A 2.50-kg steel gasoline can holds 20.0 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?

Step-by-step solution Step 1 of 8 Average density of a mixture can be found if total mass and total volume of the mixture is known. Step 2 of 8 Refers to the table 11.1 provided in the textbook. The formula to find the density of the substance is, …… (1) Here, is density, is mass and, is volume. Step 3 of 8 From table 11.1, the density of gasoline is . From equation (1), mass of 20.0L of gasoline is, Step 4 of 8 Mass of the steel is, . Therefore, the total mass is the sum of mass of steel can and mass of 20 L gasoline.
