the empirical formula of a compound is NO2. it's molecular mass is 92g/mol. What is its molecular formula?
lesantik [10]
The molecular formula:
N_x(O_2)_x

M_{N_x(O_2)_x}=x \times M_N + x \times 2 \times M_O \\ \\
m_N=14 \ \frac{g}{mol} \\
m_O=16 \ \frac{g}{mol} \\ M_{N_x(O_2)_x}=92 \ \frac{g}{mol} \\ \\
92=x \times 14+x \times 2 \times 16 \\
92=14x+32x \\
92=46x \\
\frac{92}{46}=x \\
x=2 \\ \\
N_2(O_2)_2 \Rightarrow N_2O_4

The molecular formula is N₂O₄.
