Question

three moles of hydrogen chloride having how many gram

Answer 1

Answer:

The molar mass of HCl is 36.46⋅g⋅mol−1.

Explanation:

How did I get that figure. Well, I looked up my Periodic Table, and took the sum of the atomic mass of hydrogen and chlorine: (1.00794+35.45)⋅g⋅mol−1=???

Avogadro's number = 6.022×1023⋅mol−1. How many individual HCl molecules are in a mass of 36.46⋅g of the gas?

Answer 2

Weight of H =1
Weight of chlorine = 35. 5
Therefore weight of HCl=36.5
