After immersing a cast iron weight in a beaker, the water level rose from the 50 ml mark to the 100 ml mark (determine the weight of the weight if the chigun density is p = 7g / cm3)

Data: V1 (initial volume of water in a beaker) = 50 ml (in SI system V1 = 50 * 10 ^ -6 m3); V2 (total volume of water and cast iron weight) = 100 ml (in SI system V2 = 100 * 10 ^ -6 m3).

Constants: according to the condition ρh (density of cast iron) = 7 g / cm3 (in SI system ρh = 7000 kg / m3).

To determine the mass of the cast-iron weight, we use the formula: m = V * ρh = (V2 – V1) * ρh.

Let’s calculate: m = (100 * 10 ^ -6 – 50 * 10 ^ -6) * 7000 = 0.35 kg.

Answer: A cast iron weight has a mass of 0.35 kg.
