Answer:
Step-by-step explanation:
36 grams HClX (1mole HCl /36.46097 g HCl) X (6.02 X 10^23 particles/ 1mole)
=5.943890138 X 10^23 Molecules
As there are total of two atoms in HCl molecule( one hydrogen and one chlorine,
No. of atoms in one mole of HCl = 2x5.943890138x10²³=1.188778028 x10²³ atoms. If you need it to the correct sig figs answer is 1.8 X x10²³ atoms.
here is where the numbers came from
the 1moleHCl/36.46097 g HCl is the Molar mass (get it from the periodic table
the 6.02 X 10^23 parcticle (atoms or molecules) / 1 Mole is avogadro's number
