What is the volume of the granite piece in cubic centimeters
Ghella [55]
Hi there!

Your correct answer will be 12.2 cm³.

This is how you get there:

1 mL = 1 cm³

With this one conversion factor, you can extrapolate the final answer. When you add the granite to the water, which is filled to 25.0 mL, the water level then moves to 37.2 mL. If you subtract the before volume from the volume after, you will get an answer of 12.2 mL. Then use the conversion factor and, voila! 12.2 cm³

I hope this helps!

The sucrose molecule is a large and complex molecule built of carbon, hydrogen, and oxygen. How many sucrose
jek_recluse [69]

Answer:

There are 3.01x10²³ molecules of sucrose

Explanation:

In order to calculate the number of molecules of any atom or compound, we need to use the Avogadro number which is 6.02x10²³. This number could represent atoms or molecules of any mole of compound or atom.

In other words, 1 mole of a certain atom or compound has 6.02x10²³ molecules or atoms.

we have 0.5 moles of sucrose, all we just need to do is a simple rule of 3:

If 1 mole contains 6.02x10²³ molecules

then 0.5 moles will contain:

n° molecules = 0.5 * 6.02x10²³ / 1

<h2>n° molecules = 3.01x10²³ molecules of sucrose</h2>

Hope this helps
