Q

What are the three ways you can rearrange the density formula to solve for the different variables?

A

d=m/v

v=m/d

m=d•v

17
Q

What are the units for density?

18
Q

What is the density of an object that has a mass of 3.20 g and a volume of 17.55 cm^3?

A

d = (3.20g)/(17.55cm^3)

d = 0.18 g/cm^3

19
Q

What is the density of an object that has a mass of 8.80 g and a volume of 2.20 cm^3?

A

d = (8.80g)/(2.20cm^3)

d = 4.00 g/cm^3

20
Q

What is the mass of an object that has a density of 2.35 g/cm^3 and a volume of 5.50 cm^3?

A

m = (2.35g/cm^3)•(5.50cm^3)

m = 12.93 g

21
Q

What is the mass of an object that has a density of 29.98 g/cm^3 and a volume of 14.35 cm^3?

A

m = (29.98g/cm^3)•(14.35cm^3)

m = 430.12 g

22
Q

What is the volume of an object that has a density of 10.10 g/cm^3 and a mass of 13.50 g?

A

v = (13.50g)/(10.10g/cm^3)

v = 1.37 cm^3

23
Q

What is the volume of an object that has a density of 3.45 g/cm^3 and a mass of 0.85 g?

A

v = (0.85g)/(3.45g/cm^3)

v = 0.25 cm^3

24
Q

0.0000546cm written in scientific notation is equal to what?

A

5.46 x 10-5cm

25
Q

75400L written in scientific notation is equal to what?

A

7.54 x 104 L

26

HC: What is (2.0 x 103) • (4.0 x 107)?

A

8.0 x 1010

27
Q

HC: What is (2.5 x 1014) • (7.6 x 10-22)?

A

1.90 x 10-7
