Correct answer is option D. %C= ρc (ρ- ρa)/(ρ (ρc- ρa)×100 0.5 = ρc (1.2- ρa)/1.2 (ρc- ρa)×100 0.8 = ρc (1.44- ρa)/1.44 (ρc- ρa)×100 On solving the above two equations, ρc= 1.66 and ρa= 0.94
Correct answer is option D.
%C= ρc (ρ– ρa)/(ρ (ρc– ρa)×100
0.5 = ρc (1.2- ρa)/1.2 (ρc– ρa)×100
0.8 = ρc (1.44- ρa)/1.44 (ρc– ρa)×100
On solving the above two equations,
ρc= 1.66 and ρa= 0.94
