I do it in this way:

W = ( 0.067 - 0.045 ) (9.8)

= 0.2156

Volume of aluminium = 0.067 / 2700 = 2.48 x 10-5

0.2156 = (density of turpentine ) (2.48 x 10-5) (9.8)

density of turpentine = 887

However, my lecturer do it in this way:

W = (density of aluminium) (g)(volume of solid)

volume of solid = xxx

W = (density of turpentine) ( g ) ( volume of solid)

density of turpentine = 2699.4

Which solution is correct actually?
