5. A loaf of bread has a 5. A loaf of bread has a volume of 2270.0 cmvolume of 2270.0 cm33 and and a mass of 454.0 grams. a mass of 454.0 grams. What is the density of the What is the density of the bread?bread?

Calculation #1

Density = Density = MassMass ÷ ÷ VolumeVolume

Density = Density = 4725.0 grams4725.0 grams ÷ ÷ 350.0 cm350.0 cm33

Density = Density = 13.5 g/cm13.5 g/cm33

Calculation # 2

Density = Density = MassMass ÷ ÷ VolumeVolume

Density = Density = 475.0 grams 475.0 grams ÷ ÷ 250.0 cm 250.0 cm33

Density = Density = 1. 9 g/cm 1. 9 g/cm33

Calculation # 3

Density = Density = MassMass ÷ ÷ VolumeVolume

Density = 148.0 Density = 148.0 gramsgrams ÷ ÷ 40.0 cm 40.0 cm33

Density = Density = 3.7 g/cm3.7 g/cm33

Calculation #4

Density = Density = MassMass ÷ ÷ VolumeVolume

Density = Density = 680.0 grams680.0 grams ÷ ÷ 1000.0 cm1000.0 cm33

Density = Density = 0.68 g/cm0.68 g/cm33

Calculation #5

Density = Density = MassMass ÷ ÷ VolumeVolume

Density = Density = 454.0 grams454.0 grams ÷ ÷ 2270.0 cm2270.0 cm33

Density = Density = 0.2 g/cm0.2 g/cm33
