Question
Describe an experiment to determine the density of a liquid.

Solution
To determine the density of a liquid D = M / V
We need to find (i) the vol. of liquid say milk, (ii) mass of liquid.
EXPERIMENT:
(i) To find the mass of milk:
wt. of empty 100 c.c beaker = M1 g = 70 g (say)
Fill the beaker (half) with milk and weigh again=M2 g = 116 g (say)
(ii) To find the vol. of milk:
Transfer this milk into measuring cylinder and note volume V = 40 c.c (say)
∴Density of milk =D=`M/V`=`(m_2-m_1)/(40c.c)`
=`(116-70)/40`=`46/40`=`4.6/4`=1.15 g `cm^-3`
