Answer is: 6.66 L of NH3 are needed to react completely.

Balanced chemical equation: 4NH₃ + 6NO  → 5N₂ + 6H₂O.

V(NO) = 10.0 L; volume of nitrogen(II) oxide.

V(NH₃) = ?

Vm = 22.4 L/mol; molar volume at STP.

n(NO) = V(NO) ÷ Vm.

n(NO) = 10 L  ÷ 22.4 L/mol.

n(NO) = 0.446 mol; amount of nitrogen(II) oxide.

From balanced chemical equation: n(NO) : n(NH₃) = 6 : 4

0.446 mol : n(NH₃) = 6 : 4.

n(NH₃) = 0.3 mol; amount of ammonia.

V(NH₃) = 0.3 mol · 22.4 L/mol.

V(NH₃) = 6.66 L.

An unknown gas diffuses 1.25 times faster than CO2 gas. What is the molar mass of the unknown gas?​
hodyreva [135]

Answer:

28.16 g/mol

Explanation:

From Graham's law;

Let the rate of diffusion of gas X be 1.25

Let the rate of diffusion of CO2 be 1

Molecular mass of gas X= M

Molecular mass of CO2 = 44g/mol

1.25/1=√44/M

(1.25/1)^2 = 44/M

1.5625 = 44/M

M= 44/1.5625

M= 28.16 g/mol
