Question

a substance has a mass of 15 grams and a volume of 32 ml. calculate the density of the substance.
a 2.13 g/ml
b 0.469 g/ml
c 3.79 g/ml
d 0.351 g/ml

Explanation:

Step1: Recall density formula

Density ($
ho$) is given by $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute values

Given $m = 15$ g and $V=32$ mL. So, $
ho=\frac{15}{32}$ g/mL.

Step3: Calculate result

$\frac{15}{32}= 0.46875\approx0.469$ g/mL.

Answer:

B. 0.469 g/mL
