Answer:
37.275g must react
Explanation:
Step 1: Balance the reaction
The reaction is as follow:
2 K + Cl2---------> 2KCl
This means that for 2 moles K we have 1 mole Cl2 ( and 2 moles KCl)
Step 2: Calculate moles
Moles of potassium: moles = mass / Molar mass
Moles of potassium = 41g / 39.1g/mol
Moles of potassium = 1.05 moles
for each 2 moles potassium we have 1 mole Cl2 ( and 2 moles KCl)
Moles of Chlorine : 1.05 / 2 = 0.525 moles ( and 1.05 moles of KCl)
Step 3: Calculate mass of chlorine
mass chlorine = moles x Molar mass = 0.525 x 35.5 x 2
= 37.275g Chlorine
