Answer:
2.58 g/cm^3
Step-by-step explanation:
Density of mixture of A and B = mass of mixture of A and B / Volume of mixture of A and B
(0.99+1.59) = (139+282) / V
2.58 = 419 / V
V = 419 / 2.58 = 163.4 cubic centimeters
Volume of the mixture of A and B = 163.4 cubic centimeters.
If the mixture of A and B = C, then
Density of C = mass of C / volume of C = 419/163.4 = 2.58 g/cm^3
Density of liquid C = 2.58 g/cm^3
