You are watching: What is mass per unit volume

1 density is characterized as mass per unit volume. That is a measure of exactly how tightly packed and how heavy the molecules space in an object. Thickness is the amount of issue within a particular volume. Which has actually the biggest density? Why? thickness Notes 2 3 4 Two connected terms of density 1- Mass- the lot of issue in one object; that is exactly how much stuff an item has Unit offered for massive is grams (g) and also kilograms (kg) how measured: range Which has much more mass? Why? 5 2 term connected to thickness Volume- the lot of 3-dimensional shape an item occupies deserve to be measure up by: Volume = together * W * H (box or cube) i graduated Cylinder (for a liquid) (beaker) Displacement (irregularly shaped object) systems for volume: centimeter 3, in 3, Liters (L), mL 6 Volume 1) Which has actually the biggest volume? number it out. 2) Which has the biggest volume? 7 Calculating density The formula for thickness is: thickness = mass Volume Units: g/mL, g/cm 3, kg/L 8 units for thickness g/cm 3 or g/mL Formula: M = massive V= volume D = thickness M = D x V V = M / D D = M / V 9 10 11 1)Find the fixed of the thing 2)Find the volume the the thing 3)Divide : thickness = mass - Volume come find thickness : collection up your density problems favor this: Givens: Unknown: Formula: D = M / VSolve Ex. If the massive of things is 35 grams and also it takes up 7 cm 3 of space, calculation the density. 12 calculation the volume that a liquid through a fixed of 10 g and also whose density is 2 g/mL. - givens: –unknown: –formula for unknown: –plug in values and solve. 13 To find the thickness 1- find the mass of the object- use a scale 2- uncover the volume the the object- 3- Divide density = mass Volume 14 density Units Density- the lot of fixed in a given volume. Density = massive / volume Units- kg/L or kg/m 3 g/mL or g/cm 3 15 The density of yellow is about 19 g/cm 3 1) how much would certainly 2 centimeter 3 of yellow weigh? 2) What is the massive of 1 cm 3 that gold? 16 A liquid has a thickness of 2 g/mL. What precisely does this mean? 17 A liquid has actually a thickness of 1.5 g/mL. 1)What is the mass of 1 mL of this liquid? 2) What is the massive of 2 mL of this liquid? 3) What is the massive of ½ a mL the this liquid? 18 Proof the water and ice have various densities 19 1)Find the massive of the thing 2)Find the volume the the thing 3)Divide : density = massive - Volume come find thickness : Ex.

If the mass of an item is 35 grams and also it takes up 7 centimeter 3 the space, calculate the density.
