Question 15: People carry out 3 weighings as follows using a Robecvan balance: Weighing 1: Balance plate on the left: a bottle has 250cm3 of liquid + object. Right plate: 500g weight. Weighing 2: Left pan: empty jar + object. Weight pan right: weight 300g Weight: Weight plate left: empty jar Right balance plate: weight 230g. Calculate the density of the liquid
From weighing 1 and 2 we deduce the mass of the liquid
mn = 500 – 300 = 200g.
+ Liquid volume D = 200 : 250 = 0.8g/cm3 = 800kg/m3.
The answer is NO
