An engine block made from an aluminium alloy is suspended from a spring scale in air and its mass is recorded as 20.00 kg. When the engine is submerged in water (density 999 kg/m³), the same spring scale records an apparent mass of 12.6 kg. What is the density of the aluminium alloy (to two significant figures)? Assume there is negligible buoyancy force on the engine when it is suspended in air. O 3000 kg/m ○ 4.0 x 10³ kg/m³ O 5500 kg/m³ O 2.7 x 10³ kg/m³ O None of the other answers
