One & Two Step Equations, Percent Error, Density
2
Percent Error
% error = measured value - accepted value x 100
accepted value
Measured value = "student determines," "student measures," experimental value
Accepted value = "actual value"
3
Density
D = m
v
D = density (g/mL) (g/cm3)
m = mass (g)
V = volume (mL, L, cm3)

Multiple Choice
What would be the best first step to solving the equation? -6x=-24
multiply both sides by -6
divide both sides by -6
add 6 to both sides
subtract -6 from both sides
5
Multiple Choice
What would be the best first step to solving the equation? -3=x+5
add 3 to both sides
subtract 5 from both sides
add 5 to both sides
subtract -5 from both sides

Multiple Choice
The density of liquid mercury is 1.25 g/mL. Charlotte measured a density of 1.75g/mL in lab. What is the percent error?
21%
17.37%
40%
21.02%
10
Multiple Choice
What is the formula for density?
density = mass x volume
density = mass / volume
density = mass + volume
density = mass - volume
