What is the mass of a sample with a volume of 2.45 mL and a density of 3.42 g/mL?
A) 1.40 g
B) 0.716 g
C) 8.38 g
D) 0.970 g
Density
Density is a physical property that measures the mass of a substance per unit volume, used to characterize the compactness of a material.
Volume
A measurement of the amount of space an object or substance occupies, often measured in liters, cubic meters, or gallons.
Mass
An evaluation of how much material an object holds, commonly measured in kilograms or grams.
- Employ the density formula to determine mass when given density and volume.
- Augment problem resolution skills by determining the mass of a substance based on its density and volume.

Final Answer :
C
Explanation :
The mass of the sample can be calculated using the formula mass = density × volume. Substituting the given values, mass = 3.42 g/mL × 2.45 mL = 8.379 g, which rounds to 8.38 g.
