Explanation Given data: The earth’s mass is 5.94 × 10 24 k g and the earth’s volume is 1.08 × 10 12 k m 3 . Formula used: Write the conversion factor for km to meter. 1 k m = 1 , 000 m (1) Write the expression for average density ( ρ ) . ρ = M V (2) Here, M is earth’s mass, and V is earth’s volume. Explanation: Convert 1.08 × 10 12 k m 3 to m 3 using equation (1). 1.08 × 10 12 k m 3 = 1.08 × 10 12 ( 1 , 000 m ) 3 = 1.08 × 10 21 m 3 Substitute 5
