A student is trying to figure out how many moles of potassium chloride are formed from 4.0 grams of chlorine gas. Which step in the following students work is incorrect?

Step 3 ⇒ incorrect

Given

mass of Cl₂ : 4 g

Required

incorrect step

Analysis

analyze step

Solution

Reaction

2K(s)+Cl₂(g)⇒2KCl(s)

Step 1⇒correct

we determine the moles of Cl₂ by their mass

MW of Cl₂=70.9 g/mol

mol=mass : MW

Step 2 ⇒ correct

From equation, mol ratio of Cl₂ to KCl = 1 : 2, so mol KCl :

Step 3 ⇒ incorrect
