Answer 1

The answer to your question is 2.14 moles of Cl₂

Step-by-step explanation:

Data

mass of NaCl = 250 g

moles of Cl₂ = ?

Process

1.- Write the balanced chemical reaction

2NaCl + 2H₂O ⇒ 2NaOH + Cl₂ + H₂

2.- Calculate the molar mass of NaCl

NaCl = 23 + 35.45 = 58.45 g

3.- Convert the mass of NaCl to moles

58.45 g of NaCl ---------------- 1 mol

250 g of NaCl ------------------- x

x = (250 x 1) / 58.45

x = 4.28 moles

4.- Calculate the moles of Cl₂

2 moles of NaCl ----------------- 1 mol of Cl₂

4.28 moles of NaCl ------------- x

x = (4.28 x 1) / 2

x = 2.14 moles of Cl₂
