Question

a 25.5 g sample of metal has a density of 9.80 g/ml. what is the volume of the sample in milliliters?
○ 26.0 ml
○ 2.60 ml
○ 250 ml
○ 0.250 ml

Explanation:

Step1: Recall density formula

Density formula is $
ho = \frac{m}{V}$, where $
ho$ is density, $m$ is mass, $V$ is volume. We need to solve for $V$, so rearrange the formula to $V=\frac{m}{
ho}$.

Step2: Substitute values

Given $m = 25.5\ \text{g}$, $
ho=9.80\ \text{g/mL}$. Substitute into the formula: $V=\frac{25.5\ \text{g}}{9.80\ \text{g/mL}}$.

Step3: Calculate the value

$\frac{25.5}{9.80}\approx2.60\ \text{mL}$.

Answer:

2.60 mL
