Aluminium reacts with sulfuric acid to form aluminium sulfate and hydrogen. What is the volume of hydrogen gas in liters ( L ) produced at 300 K and 1 . 0 atm pressure, when 5 . 4 g of aluminium and 50 . 0 mL of 5 . 0 M sulfuric acid are combined for the reaction? (Use molar mass of aluminium as 27 . 0 g mol - 1 , R = 0 . 082 atm L mol - 1 K - 1 )

Correct answer

0

Step-by-step solution

2 AI +   3 H 2 SO 4 ⟶ AI 2 SO 4 3 + 3 H 2 5 . 7 27 50 × 5 1000 = 0 . 2   mole = 0 .25   mole ( Limiting   reagent ) ∴ 0 .25   mole  H 2 is formed PV = nRT V = nRT P = 0 . 25 × 0 . 082 × 300 1   atm = 6 . 15 litre
