Answer to Question #266752 in Inorganic Chemistry for Student

Question

How many grams of HCl are produced when 15.2 mol H2O reacts?

HCl produced: g

How many moles of CO2 are produced when 76.5 g HCl is produced?

CO2 produced: mol

How many grams of C12H4Cl6 are reacted when 100.25 g CO2 is produced?

C12H4Cl6 reacted: g

How many grams of HCl are produced when 2.5 kg C12H4Cl6 reacts?

HCl produced:g

Answer 1

a)

Moles of H2O = 10.0 moles of O2 x 2 moles of H2O / 23 moles of O2 = 0.870 moles

b)

Moles of HCl = 15.2 moles of H2O x 12 moles of HCl / 2 moles of H2O = 91.2 moles

Mass of HCl = 91.2 moles x 36.46 g / mol = 3.33 x 10^3 g

c)

Moles of HCl = 76.5 g x 1 mol / 36.46 g = 2.10 moles

Moles of CO2 = 2.10 moles of HCl x 24 moles of CO2 / 12 moles of HCl = 4.2 moles

d)

Moles of CO2 = 100.25 g x 1 mol / 44.01 g = 2.28 moles

Moles of C12H4Cl6 = 2.28 moles of CO2 x 2 moles of C12H4Cl6 / 24 moles of CO2 = 0.19 moles

Mass of C12H4Cl6 = 0.19 moles x 360.88 g / mol = 68.6 g
