What is the formula for Density?
D=M/V

A block of aluminum occupies a volume of 15.0 mL and weighs 40.5 g. What is its density?
d=m/v
d = 40.5 g / 15.0 mL
d = 2.70 g/mL
100
Mass = ?
Volume = 60 cm3
Density = 2 g/cm3
m = V x D
m = 60 cm3 x 2 g/cm3
m = 120 g100
Mass = 120 g
Volume = ??
Density = 6 g/cm3
V = M/D
V = 120 g / 6 g/cm3
V = 20 cm3

Mercury metal is poured into a graduated cylinder that holds exactly 22.5 mL. The mercury used to fill the cylinder weighs 306.0 g. From this information, calculate the density of mercury.
d=m/v
d = 306.0 g / 22.5 mL
d = 13.6 g/mL

7) Find the mass of 250.0 mL of benzene. The density of benzene is 0.8765 g/mL.
d = g / mL
g = (d) (mL)
g = (0.8765 g/mL) (250.0 mL) = 219.1 g

What volume of silver metal will weigh exactly 2500.0 g. The density of silver is 10.5 g/cm3.
d = M / V
V = M / D
V = 2500.0 g / 10.5 g/cm3
V = 238 cm3

Calculate the density of sulfuric acid if 35.4 mL of the acid weighs 65.14 g.
d=m/v
d = 65.14 g / 35.4 mL
d = 1.84 g/mL

Mass = 639 g
Volume = ??
Density = 10.143 g/cm3
V = M/D
V = 639 g / 10.143g/cm3
V = 62.999 cm3

How do you get the mass formula from the density formula?
D=M/V --> multiply both sides by VOLUME to make --> M=V x D

Mass = ?
Volume = 59 cm3
Density = 6.695 g/cm3
M = D x V
M = 59 cm3 x 6.695 g/cm3
M = 395.005 g

Which of Ms. McCall's Dogs is the most "dense" based off of size alone.
Lulu
500
how do you get the volume formula when given the density formula?
Start with the Density Formula: D = M/V --> Multiply both sides by VOLUME to get --> M = D x V. --> Then DIVIDE both sides by density to get volume by itself --> Giving you the Volume Formula V = M/D

Mass: 924 g
Volume: 89 cm3
Density: ??
d=m/v
d= 924 g / 89cm3
d = 10.382 g/cm3
500
Mass = ?
Volume = 128 cm3
Density = 9.45 g/cm3
M = V x D
M = 128 cm3 x 9.45 g/cm3
M = 1,209.6 g
500
Mass = 763 g
Volume = ??
Density = 49.12 g/cm3
V = M/D
V = 763 g / 49.12 g/cm3
V = 15.533 cm3
