What is the weight of 0.5 liters of alcohol, milk, mercury?

Given:

rsp = 800 kg / m3
pm = 1030 kg / m3
ppm = 13600 kg / m3
V = 0.5 l = 0.0005 m3

The notation used in this problem: psp is the density of alcohol, pm is the density of milk, ppm is the density of mercury

Find: msp; mm; mrt
msp – mass of alcohol, mm – mass of milk, mrt – mass of mercury

Let’s use the formula to calculate the mass: m = рV
msp = 800 • 0.0005 = 0.4 kg
mm = 1030 • 0.0005 = 0.515 kg
mrt = 13600 • 0.0005 = 6.8 kg
