A certain piece of metal has a mass of 282.5g,If when the block was totally immersed in overflow can displaced water in a beaker of mass 20g. If the mass of water and the beaker was 45g, Find the Relative density of the metal.
Answers
Answer:
figure below Shows two identical flasks one filled with water to 250cm3 mark and the other filled with kerosene to the same 250cm3 mark, when measured in electronic balance the flask filled with water is found to be heavier than that filled with kerosene why? The answer is in finding the mass per unit volume of kerosene and water in respective flasks.
The mass of the flask filled with water is 330g, and the mass of flask filled with kerosene 280g, the empty flasks were measured and found to be 80g therefore mass of water only is 250g and kerosene only is 200g.
Mass per unit volume of water is 250g/ 250cm3 this is 1g/cm3.
Mass per unit volume of kerosene is 200g/ 250cm3this is 0.8g/cm3.
The results 1g/cm3 and 0.8g/cm3 are the densities of water and kerosene respectively.
