Recently, one of Secondary 4 students asked me a question on Salts Solubility that is related to Mole Calculations, and i would like to share with you on the thought process to solve such a question.
Question:
Excess amount of water was added to a mixture consisting of sodium chloride, sodium sulfate and silver chloride salts. The solution that is formed is known to contain 0.4 mol of chloride ions and 0.6 mol of sulfate ions. What is the number of moles of sodium ions present in the solution?
A) 0.4 mol
B) 1.0 mol
C) 1.4 mol
D) 1.6 mol
Now, stop scrolling and start trying out the question first, before you scroll down to look at the suggested solution!
