How many molecules are in 100 grams of HCl?

1.65 x 10^24 molecules in 100 grams of HCL
because HCL is 36.461 grams/mol
and there are 6.02 x 10^23 molecules/ mol
if you did stochiometry this is what you will get 1.65 x 10^24
hope i helped

The number of molecules that are present in 100g of HCl is 16.5×10²³.
What is Avogadro's number?
Avogadro's number is the number of entities which are present in 1 mole of any substance and it is equal to 6.022×10²³ .
For this question moles of HCl will be calculated as:
n = W/M, where

W = given mass = 100g
M = molar mass = 36.45g/mol

n = 2.74 mol
Now number of molecules in this given moles will be calculated as:
No. of molecules = (2.74)(6.022×10²³) = 16.5×10²³
Hence required number of molecules are 16.5×10²³.

In 100 grams of HCl, there are approximately 16.5 x 10²³ molecules. This is calculated by first determining the molar mass of HCl and converting grams to moles, then using Avogadro's number to find the number of molecules. The molar mass of HCl is about 36.46 g/mol, leading to the calculation of around 2.74 moles in 100 grams.
