Question

What is the density of a sample with a mass of 24.47 g and a volume of 13.2 mL?

A. 1.85 g/mL
B. 0.54 g/mL
C. 1.85 g/cm³
D. 0.54 g/cm³

Answer 1

The density of the sample is 1.85 g/mL, calculated by dividing the mass (24.47 g) by the volume (13.2 mL). Thus, the correct answer is A. 1.85 g/mL, which is also equivalent to C. 1.85 g/cm³.

Step-by-step explanation:

The density of a sample is calculated using the formula density = mass/volume. In this case, the given mass is 24.47 grams (g) and the volume is 13.2 milliliters (mL). To find the density, divide the mass by the volume:

Density = 24.47 g / 13.2 mL = 1.85378788 g/mL

When rounded to two decimal places, the density is 1.85 g/mL. Therefore, the correct answer is A. 1.85 g/mL. Note that 1 mL is equivalent to 1 cm³, so the density can also be expressed as 1.85 g/cm³, which corresponds to answer C.
