Question

Stoichiometry Practice: I have the answers I just need to know how to show my work. Can someone send me a pic of the shown work for these 2 problems?

Answer 1

Answers:

1.

The mole ratio of AlCl₃ to Cl₂ is 2 : 3. This means for production of every 2 moles of AlCl₃ 3 moles of Cl₂ is consumed. Hence, if 3 moles of AlCl₃ is produced then Cl₂ consumed is,

                               = 3 × 3 / 2

                               = 4.5 moles of Cl₂

2.

Mole ratio of C₃H₈ to CO₂ is 1 : 3.

Hence, 0.5 moles of C₃H₈ will produce 1.5 moles of CO₂.

Also,

At STP one mole of an ideal gas occupied 22.4 L of volume. Hence, 1.5 moles of CO₂ gas will occupy,

Volume = 1.5 mol × 22.4 L/mol

Volume = 33.6 L of CO₂
