Question

calculate the density of an object, if the mass is 183 g and the volume is 21 ml. density = \frac{mass}{volume} remember to select an answer with the correct number of significant figures. 0.11 g/ml 8.7 g 0.11 ml 8.7 g/ml i dont know yet

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute values

Given $m = 183$ g and $V=21$ mL, so $
ho=\frac{183}{21}\text{ g/mL}$.

Step3: Calculate result

$\frac{183}{21}\approx8.714$ g/mL. Rounding to two significant - figures (since 21 has two significant figures), we get $
ho = 8.7$ g/mL.

Answer:

D. 8.7 g/mL
