What are the steps to measure the density of a solid?

Chemistry

JulsSmile [24]2 years ago

Answer:

Look below

Explanation:

The formula for density is:

Density=\frac{mass}{volume}

Therefore in order to find the density of a solid, you must find the mass and the volume first.

To find the mass, you can use a scale.

To find the volume, you can use the water displacement method. For example, if you fill the water of a graduated cylinder to 10 mL, and then you put a rock inside, and it rises to 15 mL, then the volume (of the rock) is 15mL-10mL=5mL.

Drupady [299]

Answer:

Root mean squared velocity is different.

Explanation:

Hello!

In this case, since we have a mixture of oxygen and nitrogen at STP, which is defined as a condition whereas T = 298 K and P = 1 atm, we can infer that these gases have the same temperature, pressure, volume and moles but a different root mean squared velocity according to the following formula:

v_{rms}=\sqrt{\frac{3RT}{MM} }

Since they both have a different molar mass (MM), nitrogen (28.02 g/mol) and oxygen (32.02 g/mol), thus we infer that nitrogen would have a higher root mean squared velocity as its molar mass is less than that of oxygen.

Best regards!
