Question

which is the correct equation for calculating density? 10 points density = mass/volume density = mass/weight density = volume/mass density = volume/weight what is the density of an object whose mass is 180 grams and whose volume is 45 cm^3? 10 points 4cm/g 0.25 g/cm^3 4 g/cm^3 0.25 cm^3/g weight is a flawed measure of mass because it * 10 points is not used in other countries is affected by the force of gravity tends to fluctuate can be influenced by temperature and pressure

Explanation:

Step1: Recall density formula

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

Step2: Solve first - question

Based on the formula, the correct equation for calculating density is Density = Mass/Volume.

Step3: Solve second - question

Given $m = 180$ g and $V=45$ cm³. Using $
ho=\frac{m}{V}$, we substitute the values: $
ho=\frac{180\text{ g}}{45\text{ cm}^3}=4$ g/cm³.

Step4: Solve third - question

Weight $W = mg$, where $g$ is the acceleration due to gravity. Since $g$ can vary depending on location (e.g., different on Earth and Moon), weight is affected by the force of gravity and is a flawed measure of mass.

Answer:

1. Density = Mass/Volume
2. 4 g/cm³
3. is affected by the force of gravity
