“The Density Equation” Mass (g) Volume (mL or cm 3 ) Density (g/mL or g/cm 3 )

Liquid - Liquid - graduated cylinder Read at the meniscus Regular Solid - L x W x H = cm 3 Irregular Solid - displacement

Let’s Practice… If the mass of an object is 6 grams and the volume is 3 mL, what is the density of the object? Step 1 Step 2 Step 3Step 4 m = V = D = D = m 1 V D = 6g 3mL D = 2 g/mL 6g 3mL ?

Let’s Practice… If the density of an object is 2 g/mL and the volume is 4 mL, what is the mass of the object? Step 1 Step 2 Step 3Step 4 m = V = D = m = 8 g/mL ? 4mL 2 g/mL

Let’s Practice… If the density of an object is 5 g/mL and the mass is 15 g, what is the volume of the object? Step 1 Step 2 Step 3Step 4 m = V = D = V = 1 mL 15g ? 15 g/mL

1. 1. If the mass of an object is 20 g and the volume of the object is 50 cm 3, what is the density? Will it sink or float in H 2 O? If the mass of an object is 12 g and the dimensions are 2cm x 2cm x 3cm, what is the density of the object? What is the mass of an object with a volume of 2 cm 3 and a density of 6 g/cm 3 ? What is the volume of a object with a mass of 24 g and a density of 8 g/mL?
