Question

practice 8 - find the density
find the density of each liquid and then organize it by most dense (1) to least dense (3).

1. honey: 136 g; 100 ml
2. water: 150 ml; 150 g
3. ocean water: 100 ml; 103 g

essential question: how is matter measured?

Explanation:

Step1: Recall density formula

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

Step2: Calculate density of honey

For honey, $m = 136$ g and $V=100$ mL. So, $
ho_{honey}=\frac{136\ g}{100\ mL}=1.36$ g/mL.

Step3: Calculate density of water

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

Step4: Calculate density of ocean - water

For ocean - water, $m = 103$ g and $V = 100$ mL. So, $
ho_{ocean - water}=\frac{103\ g}{100\ mL}=1.03$ g/mL.

Step5: Organize by density

Comparing the densities: $1.36>1.03 > 1$. So, the order from most dense (1) to least dense (3) is: Honey (1), Ocean Water (2), Water (3).

Answer:

Honey (1), Ocean Water (2), Water (3)
