Answer:

Mole Concept

n = N/NA ...

Molar mass of a Substance = (Mass of the Substance in grams)/(Number of Moles) ...

Number of Moles = (Mass of the Sample)/(Molar Mass) ...

Number of Atoms or Molecules = (Number of Moles)*(6.022*1023) ...

1 amu = (1gram)/(6.022*1023) = 1.66*10-24 grams.

Explanation:

Answer:

A mole is a unit of measurement in chemistry. Here is the official definition: One mole of something (say, atoms, or raindrops) is equal to as many of that something as there are atoms in 12 grams of the isotope carbon-12.

Experiments have nailed down the number as 6.02 times 10 to the 23rd power, or 6.02x1023 in mathematical notation. So, in other words, one mole of atoms of carbon-12 is 6.02x1023 carbon atoms. (Altogether, that many atoms weigh 12 grams.) A mole of pumpkin spice lattes, to use a seasonally appropriate reference, is 6.02x1023 pumpkin spice lattes. That many lattes weighs a lot more than 12 grams, though. More on that later.
