Answer:
0.024 g/mL
Explanation:
The denisty of a substance is a ratio comparing its mass per every 1 unit of volume. Therefore, if you have been given a mass in grams and a volume in milliliters, the unit for denisty (in this case) is g/mL.
Density = ? grams / ? mL
Density = 12 g / 500 mL
Density = 0.024 g/ 1 mL = 0.024 g/mL
