Calculate moles of Fe in 5.22 X 10^22 atoms of Fe?
Setler [38]

Answer:

The amount of moles of Fe in 5.22*10²² atoms of Fe is 0.0867.

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 6.023*10²³ atoms are contained in 1 mole, 5.22*10²² atoms are contained in how many moles?

amount of moles=\frac{5.22*10^{22}atoms * 1 mole}{6.023*10^{23}atoms}

amount of moles= 0.0867

<u><em>The amount of moles of Fe in 5.22*10²² atoms of Fe is 0.0867.</em></u>

Which instrument below is used to measure an intensive property?
Andrei [34K]

An intensive property is the physical characteristics that have an independent magnitude. The thermometer can be used to measure the temperature. Thus, option C is correct.

<h3>What is an intensive property?</h3>

An intensive property has been constituted of the parameters that are not dependent on the size and the mass of the sample. Density, pressure, and temperature are some intensive properties.

The first image shows a weighing balance, the second shows a volumetric cylinder, and the fourth shows a ruler used to measure mass, volume, and length respectively, which are extensive properties.

Therefore, option C. thermometer measures temperature, which is an intensive property.
