Question

question 1
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.
answer
0.11 g/ml
8.7 g/ml
0.11 ml
8.7 g

Explanation:

Step1: Identify the formula

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

Step2: Substitute values

Given $m = 183$ g and $V=21$ mL. Substitute into the formula: $
ho=\frac{183}{21}\text{ g/mL}$.

Step3: Calculate the 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:

8.7 g/mL
