Question

Dexter is coming up with a chemical complex using 3 different soluble substances in the volume ratio 3:4:7. The densities of these substances are in the ratio 5:2:6 respectively. The mass of the $2^{n d}$ substance contained in 130 litres of the complex is ___

Options:

Answer: Option A
:

$D e n s i t y = \frac{M a s s}{V o l u m e}$

Individual volume ratio = volume of component

Total volume

Ratio of volumes $= \frac{3}{14} : \frac{4}{14} : \frac{7}{14}$

Ratio of densitites $= \frac{5}{13} : \frac{2}{13} : \frac{6}{13}$

Ratio of masses $= \frac{3}{14} \times \frac{5}{13} : \frac{4}{14} \times \frac{2}{13} : \frac{7}{14} \times \frac{6}{13} = 15 : 8 : 42$ . mass in $2^{n d}$ substance $= \frac{8}{65} \times 130 = 16$ litres.
