How can you find atoms and molecules?

Question

Ellie Andrews · Accepted Answer

Well you can find atoms and molecules, using the Avogadro's constant;

Applying this equation; #"No of moles" = "Atoms"/"Avogadro's constant"# Where, Avogadro's constant is #6.023 xx 10^-23#

Ellie Andrews · Answer

Refer to the explanation.

Avogadro's number can be used to calculate the number of atoms or molecules if you know the moles of atoms or molecules: For instance How many atoms are in #"5.0 mol Cu"#? #5.0color(red)cancel(color(black)("mol Cu"))xx(6.022xx10^23"atoms Cu")/(1color(red)cancel(color(black)("mol Cu")))=3.0xx10^24" atoms Cu"# Example Two How many molecules are in #"3.5 mol C"_6"H"_12"O"_6#? #3.5color(red)cancel(color(black)("mol C"_6"H"_12"O"_6))xx(6.022xx10^23"molecules C"_6"H"_12"O"_6)/(1color(red)cancel(color(black)("mol C"_6"H"_12"O"_6)))=2.1xx10^24" molecules C"_6"H"_12"O"_6"#

undefined Atoms and molecules can be found using various experimental techniques such as spectroscopy, microscopy, and mass spectrometry. These methods involve analyzing the properties of matter, such as their electromagnetic interactions or mass-to-charge ratios, to identify and characterize individual atoms and molecules. Additionally, chemical reactions can be used to infer the presence and composition of molecules based on the products formed.
