Question

Given the equation: KOH + NaCl ➞ KCl + NaOH, if 27.7 grams of sodium chloride are provided and you want grams of potassium chloride, what is the correct procedure to get the answer?

a) mol of KOH --> grams of KOH --> grams of KCl --> mol of KCl
b) grams of KOH --> mol of KOH --> mol of KCl --> grams of KCl
c) grams of NaCl --> mol of NaCl --> mol of KCl --> grams of KCl
d) grams of NaCl --> mol of KOH --> grams of NaOH --> grams of KCl

Answer 1

The correct procedure to get the answer is to convert grams of NaCl to moles of NaCl, then convert moles of NaCl to moles of KCl using the mole ratio from the balanced equation, and finally convert moles of KCl to grams of KCl.

Step-by-step explanation:

The correct procedure to get the answer is:

1. Convert grams of NaCl to moles of NaCl.
2. Convert moles of NaCl to moles of KCl using the mole ratio from the balanced equation.
3. Convert moles of KCl to grams of KCl.

Therefore, the correct option is b) grams of KOH --> mol of KOH --> mol of KCl --> grams of KCl.
