Answer 1

The density of liquid C at the given mass and volume is 1.6 g/cm³.

The given parameters:

• Density of liquid A, = 1.8 g/cm³
• Density of liquid B, = 1.2 g/cm³
• Volume of liquid C, = 120 cm³

Mass of liquid C

The mass of liquid C is calculated as follows;

$mass =density \times volume\\\\mass _{C} = (1.8 \times 80 ) + (1.2 \times 40)\\\\mass _{C} = 192 \ g$

The density of liquid C

The density of liquid C is calculated as follows;

$Density = \frac{mass}{volume} \\\\Density_{C} =\frac{192 \ g}{120 \ cm^3} = 1.6 \ g/cm^3$
