Answer to Question #319319 in Chemistry for Eya

Question

molar mass of KCI

Answer 1

Solution:

The atomic mass of potassium (K) is equals to 39.0983 atomic mass units

The atomic mass of chorine (Cl) is equals to 35.453 atomic mass units

Therefore,

Molar mass of KCl = Atomic mass of K + Atomic mass of Cl = 39.0983 + 35.453 = 74.5513

Answer: The molar mass of KCl is 74.55 g/mol
