A 6 g object has a density of 2 g/mL. Find its volume.
m = 6 g
D = 2 g/mL
v = ? (your unknown)
What equation will you use?
- D = m/v
- Q = (m)(ΔT)(Cp)
- S = D/T
- a = (Δv)/(Δt)
- p = mv
- F = ma
- W = Fd
A 6 g object has a density of 2 g/mL. Find its volume.
m = 6 g
D = 2 g/mL
v = ? (your unknown)
Equation: D = m/v
What does "m/v" mean?
- m + v
- m - v
- m x v
- m ÷ v
A 6 g object has a density of 2 g/mL. Find its volume.
m = 6 g
D = 2 g/mL
v = ? (your unknown)
Equation: D = m/v
Which of the following is correct?
- D = 6/2
- D = 2/6
- 6 = m/2
- 2 = m/6
- D = 6/ 2
- 2 = 6/v
A 6 g object has a density of 2 g/mL. Find its volume.
m = 6 g
D = 2 g/mL
v = ? (your unknown)
Equation: D = m/v
2 = 6/v
It will take two steps to solve for "v". First you have to get "v" on top.
Which of the following is correct?
- 2v = 6
- 2/v = 6
- 2 = 6v
- 2 - v = 6
- 2 x 6 = v
A 6 g object has a density of 2 g/mL. Find its volume.
m = 6 g
D = 2 g/mL
v = ? (your unknown)
Equation: D = m/v
2 = 6/v
2v = 6
Now that "v" is on top, you can solve for "v"?
Which of the following is correct?
- v = 6/2
- v = 6 x 2
- v = 6 - 2
- v = 6 + 2
A 6 g object has a density of 2 g/mL. Find its volume.
m = 6 g
D = 2 g/mL
v = ? (your unknown)
Equation: D = m/v
2 = 6/v
2v = 6
v = 6/2
So, v = ___ (no units, yet)
- 3
- 4
- 8
- 12
A 6 g object has a density of 2 g/mL. Find its volume.
m = 6 g
D = 2 g/mL
v = ? (your unknown)
Equation: D = m/v
2 = 6/v
2v = 6
v = 6/2
So, v = 3 __
What are the units for volume?
