Will it float in water? Determine if the following shapes will float in water by calculating the density for each item. D = M / V Mass: 15 g Volume: 20 mL Mass: 1000 g Volume: 50 mL Mass: 225 g Volume: 100 mL Mass: 10 g Volume: 200 mL www.middleschoolscience.comwww.middleschoolscience.com 2008

Will it float in water? Determine if the following shapes will float in water by calculating the density for each item. D = M / V Mass: 15 g Volume: 20 mL Density: 0.75 g/mL Mass: 1000 g Volume: 50 mL Density: 20.0 g/mL Mass: 225 g Volume: 100 mL Density: 2.25 g/mL Mass: 10 g Volume: 200 mL Density: 0.05 g/mL www.middleschoolscience.comwww.middleschoolscience.com 2008 If the density is less than 1.0 g/cm 3 then it will float. 1 g/mL = 1 g/cm 3
