a block of aluminum occupies a volume of 15.0 ml and weighs 40.5 g. what is its density?
Answer: Density is defined as mass per unit volume. In this case, the mass of the aluminum block is 40.5 grams, and its volume is 15.0 ml. To calculate the density, you can use the formula:
Density = Mass / Volume
Plugging in the values:
Density = 40.5 g / 15.0 ml
Density = 2.7 g/ml
Therefore, the density of the aluminum block is 2.7 grams per milliliter.
