Multiple Choice
A sample has a mass of 25 g and a volume of 2.8 mL. What is the density of this sample?
A
22.2 g/mL
B
0.11 g/mL
C
7.1 g/mL
D
8.9 g/mL
Verified step by step guidance1
Recall the formula for density, which is defined as mass divided by volume: \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
Identify the given values from the problem: mass = 25 g and volume = 2.8 mL.
Substitute the given values into the density formula: \(\text{Density} = \frac{25\ \text{g}}{2.8\ \text{mL}}\).
Perform the division to find the density value (do not calculate the final number here, just set up the expression).
Express the density with the correct units, which will be grams per milliliter (g/mL).
