How many moles of hcl are in 7. 80 x 1022 molecules?.
Yanka [14]

Taking into account the definition of Avogadro's Number, 7.80×10²² molecules of HCl  are contained in 0.1295 moles of HCl.

<h3>Avogadro's Number</h3>

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 applies to any substance.

<h3>This case</h3>

Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 7.80×10²² molecules are contained in how many moles of HCl?

amount of moles of HCl= (7.80×10²² molecules × 1 mole)÷ 6.023×10²³ molecules

<u><em>amount of moles of HCl= 0.1295 moles</em></u>

Finally, 7.80×10²² molecules of HCl  are contained in 0.1295 moles of HCl.

Which of the following tests is used to measure lateral speed and agility
kogti [31]

To measure lateral speed and agility we use the Lower extremity functional test (LEFT). This is further explained below.

<h3>What is lateral speed?</h3>

Generally,  Obtain your maximum lateral speed by increasing your acceleration. The capacity of an athlete to attain maximal speed while maintaining a forward body position and a forward visual concentration is what we mean when we talk about lateral acceleration.

In conclusion, We utilize something called the Lower Extremity Functional Test to evaluate lateral speed as well as agility (LEFT).
