Question

1. after an object of with a mass of 40.211 g is placed in a graduated cylinder containing water. the water level rises to 50.17 ml. the density of the object is 10.8 g/cm³. determine the initial level of water in the graduated cylinder.

Explanation:

Step1: Calculate object volume

Use density formula $
ho=\frac{m}{V}$, rearrange to $V=\frac{m}{
ho}$.
$V=\frac{40.211\ \text{g}}{10.8\ \text{g/cm}^3} \approx 3.723\ \text{cm}^3 = 3.723\ \text{mL}$

Step2: Find initial water volume

Subtract object volume from final volume.
$V_{\text{initial}} = 50.17\ \text{mL} - 3.723\ \text{mL}$

Answer:

$46.45\ \text{mL}$
