Answer to Question #109289 in Organic Chemistry for Salmah

Question

2NF3(g) + 3H(g). =. N2(g) + 6HF(g)

If 15.008 L of hydrogen gas is consumed at STP, how many moles of HF would be formed? ( Show full working with the formulas)

Answer 1

2NF_{3 (g)} + 3H_{2 (g)} = N_{2 (g)} + 6HF _(g)

n(H₂) = PV / RT = 100 × 15.008 / ( 8.314 × 273.15 ) = 0.66 mol

n(HF) = 2 × n(H₂) = 0.66 × 2 = 1.32 mol

Answer: 1.32 mol.
