Question

calculate the density of an object, if the mass is 34.8 g and the volume is 6.2 ml.
density = \frac{mass}{volume}
remember to select an answer with the correct number of significant figures.

Explanation:

Step1: Identify the mass and volume values

Mass $m = 34.8$ g, Volume $V=6.2$ mL

Step2: Apply the density formula

Density $
ho=\frac{m}{V}=\frac{34.8\text{ g}}{6.2\text{ mL}}$

Step3: Calculate the density

$\frac{34.8}{6.2}= 5.6129$ g/mL. Rounding to two - significant figures (since 6.2 has two significant figures), we get $
ho = 5.6$ g/mL

Answer:

5.6 g/mL
