Question

alculate the density of the following objects.
object\tmass (g)\tvolume (ml)\tdensity (g/ml)
oxygen\t1.4\t1000\tstart typing here...
water\t150\t150

Explanation:

Step1: Recall density formula

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

Step2: Calculate density of oxygen

For oxygen, $m = 1.4$ g and $V=1000$ mL. So $
ho_{oxygen}=\frac{1.4}{1000}= 0.0014$ g/mL.

Step3: Calculate density of water

For water, $m = 150$ g and $V = 150$ mL. So $
ho_{water}=\frac{150}{150}=1$ g/mL.

Answer:

Oxygen density: 0.0014 g/mL
Water density: 1 g/mL
