The density of air at room temperature is about 1.2 g/cm³.Estimate the mass of air inside a 0.80-m³volume refrigerator.(There are 1 million cm³ in 1 m³.) A)0.96 g B)960 kg C)1000 kg D)more than 1000 kg

Question

We can use the formula:
mass = density x volume
Since we are given the density in units of g/cm^3, we need to convert the volume from m^3 to cm^3:
0.80 m^3 = 0.8 x 10^6 cm^3
mass = 1.2 g/cm^3 x 0.8 x 10^6 cm^3
mass = 960,000 g
To convert to kg, we divide by 1000:
mass = 960 kg.

Therefore, the best choice is B) 960 kg.

The Density of Air at Room Temperature Is About 1
