Question

If 0.44 g of a colourless oxide of nitrogen occupies 224 mL at 1520 mm Hg and 273° C, then the compound is

(a) N₂O

(b) NO₂

(c) NO₄

(d) N₂O₂

Answer 1

Correct option is (A) \(N_2O\)

 Using Ideal gas equation.

PV = nRT

\(\Rightarrow\) \(\frac{1520}{760}atm\times 0.224 L=\frac{0.44}{M}\times0.082\times546\)

M = 44g.

molecular weight of \(N_2O=44g\)

\(\therefore\) the compound is \(N_2O.\)

Answer 2

Correct option is (a) \(N_2O\)
