Question

given that a spherical object has a density of 2.44 g/ml and a mass of 12.7 grams, calculate the volume of the object.
a 4.83 ml
b 0.184 ml
c 5.20 ml
d 0.782 ml

Explanation:

Step1: Recall density formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume. We need to solve for $V$, so we can re - arrange the formula to $V = \frac{m}{
ho}$.

Step2: Substitute given values

We are given that $m = 12.7$ grams and $
ho=2.44$ g/mL. Substituting these values into the formula $V=\frac{m}{
ho}$, we get $V=\frac{12.7}{2.44}$.

Step3: Calculate the volume

$V=\frac{12.7}{2.44}\approx5.20$ mL.

Answer:

C. 5.20 mL
