Answer:

Density = 1.052 g/cm³

Step-by-step explanation:

Density = Mass/Volume

=> Mass = Density * Volume

Mass of Ethanol:

Mass = 80 * 1.09

Mass = 87.2 g

Mass of Propylene:

Mass = 148 * 0.97

Mass = 152.58 g

Mass of Antifreeze:

Mass = 87.2+152.58

Mass = 239.777 g

Density of Antifreeze:

Density = 239.777/228

Density = 1.052 g/cm³
