Density
Multiple Choice
Given a graph showing that an object has a mass of 120 g and a volume of 40 mL, what is the density of the object?
A
160 g/mL
B
3 g/mL
C
0.33 g/mL
D
80 g/mL
Verified step by step guidance1
Identify the given quantities from the problem: mass (m) = 120 g and volume (V) = 40 mL.
Recall the formula for density, which is the ratio of mass to volume: \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
Substitute the given values into the density formula: \(\text{Density} = \frac{120\ \text{g}}{40\ \text{mL}}\).
Perform the division to find the density value (do not calculate the final number here, just set up the expression).
Interpret the units of the result as grams per milliliter (g/mL), which is the standard unit for density in this context.
