Answer to Question #225642 in Molecular Physics | Thermodynamics for eren

Question

A 5 kg plastic tank that has a volume of 0.2 m³ is filled with liquid water. Assuming the density of water is 1000 kg/m³, determine the mass in kg of the combined system

Answer 1

mass of water = density × volume

mass of water = 1000 × 0.2 = 200kg

mass of tank = 5kg

Total mass = mass of water + mass of tank = $200 + 5$ = $205\ kg$
