Answer:
0.25 mL
Step-by-step explanation:
Since the density is a ratio comparing the mass (g) of the object per every 1 mL, you can use it to convert the given mass (3 grams) to volume. In other words, you can find the volume by multiplying the given mass by the density. It is important to arrange the ratio in a way that allows for the cancellation of units (grams should be in the denominator).
Density = 12.02 g/mL
3 grams 1 mL
---------------- x ---------------------- = 0.25 mL
12.02 grams
*0.2 mL is the answer with 1 sig fig
