Question

a block has a volume of 25.3 cm³. its mass is 21.7 g. calculate the density of the block. 3.6 g/cm³ 47.0 g/cm³ 0.858 g/cm³ 579.01 g/cm³ rewatch submit

Explanation:

Step1: Recall density formula

The formula for density $
ho$ is $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute given values

Given $m = 21.7$ g and $V=25.3$ cm³, so $
ho=\frac{21.7}{25.3}$.

Step3: Calculate the result

$
ho=\frac{21.7}{25.3}\approx0.858$ g/cm³

Answer:

C. 0.858 g/cm³
