if an object is 2.65 ml and 2.45 g, what is its density?
0.200 g/ml
0.925 g/ml
1.08 g/ml
1.35 g/ml

Explanation:

Step1: Recall density formula

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

Step2: Substitute values

Given $m = 2.45$ g and $V=2.65$ mL. So $
ho=\frac{2.45}{2.65}\text{ g/mL}$.

Step3: Calculate result

$\frac{2.45}{2.65}\approx0.925$ g/mL.

Answer:

B. 0.925 g/mL
