Question

1. a cork has a mass of 3 grams and a volume of 16 cm³. calculate the density. 4. a thin glass bottle holds 25 ml of liquid and has a mass of 19 grams. calculate the density.

Explanation:

3.

Step1: Recall density formula

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

Step2: Identify mass and volume values

Given $m = 3$ g and $V=16$ cm³.

Step3: Calculate density

$
ho=\frac{3}{16}= 0.1875$ g/cm³

Step1: Recall density formula

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

Step2: Identify mass and volume values

The mass $m = 19$ g and the volume $V = 25$ ml. Since 1 ml = 1 cm³, $V = 25$ cm³.

Step3: Calculate density

$
ho=\frac{19}{25}=0.76$ g/cm³

Answer:

$0.1875$ g/cm³
