Question

A half liter bottle has mass of 90g. it contains 500cm3 of liquid when full. the bottle is filled with olive oil of density = 0.90g/cm3. calculate the mass of the oil in the bottle and calculate the mass of the full bottle

Answer 1

When the bottle is half filled it will occupy oil Half of its volume ie 250 cm^3. So mass of oil when half milled = vol * density = 0.90 *250 = 225 g

2 ) mass of full bottle = mass of bottle + mass of oil present in it = (90+225)g = 315 g
