How many chlorine atoms are found in 8.3 moles of chlorine?
erik [133]

Answer:

5*10²⁴ chlorine atoms are found in 8.3 moles of chlorine.

Explanation:

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 1 mole of the compound contains 6.023 * 10²³ atoms, 8.3 moles of the compound how many atoms does it have?

amount of atoms=\frac{8.3 moles*6.023*10^{23}atoms }{1 mole}

amount of atoms≅ 5*10²⁴ atoms

<u><em>5*10²⁴ chlorine atoms are found in 8.3 moles of chlorine.</em></u>

If a calm person with a lung capacity of 3.5 liters and a body temperature of 360 C gets angry, what will the volume of the pers
tester [92]

The volume of the person's lungs if the temperature rises from 36°C to 39°C is 3.53L and will likely not explode.

<h3>How to calculate volume?</h3>

The volume of a substance can be calculated using the following formula:

V1/T1 = V2/T2

Where;

  • V1 = initial volume
  • V2 = final volume
  • T1 = initial temperature = 36 + 273 = 309K
  • T2 = final temperature = 39 + 273 = 312K

3.5/309 = V2/312

309V2 = 1092

V2 = 1092 ÷ 309

V2 = 3.53L

Therefore, the volume of the person's lungs if the temperature rises from 36°C to 39°C is 3.53L and will not explode.
