K.C.S.E Physics Q & A - MODEL 2010PP1QN16

​In an experiment to determine the density of sand using a density bottle, the following
measurements were recorded:
Mass of empty density bottle = 43 .2g
Mass of density bottle full of water = 66.4g
Mass of density bottle with some sand = 67.5g
Mass of density bottle with the sand filled up with water = 823g
Use the above data to determine the

​(a) mass of water that completely tilled the bottle; 
(b) volume of water that completely filled the bottle; 
(c) volume of the density bottle; 
(d) mass of sand; 
(e) mass of water that filled the space above the sand; 
(f) volume of the sand; 
(g) density of the sand.
