question 21\n4 pts\nwhat is the density of a block whose mass is 45 g and has a volume of 15 cm3\n3 g/cm3\n675 g/cm3\n30 g/cm3\n0.333 g/cm3
Answer
Answer:
A. 3 g/cm3
Explanation:
Step1: Recall density formula
$\rho=\frac{m}{V}$ (where $\rho$ is density, $m$ is mass, $V$ is volume)
Step2: Substitute values
$m = 45$ g, $V=15$ cm³, so $\rho=\frac{45}{15}$
Step3: Calculate result
$\frac{45}{15}=3$ g/cm³
