Asample of ammonia has a mass of 43.5 g. how many molecules are in this sample?

Mass of ammonia sample is 43.5 g. The molecular formula of ammonia is . The molecular formula is 17.031 g/mol.

To calculate the number of molecules of ammonia, first calculate the number of moles as follows:

Here, m is mass and M is molar mass, putting the values,

Now, in mole there are molecules, this is known as Avogadro's number.

Since,

Thus,

Therefore, number of molecules in the sample will be

lol idk man i guess u gotta ask bill nye the science guy
