Assume that the NO, concentration in a house with a gas stove is 150 pg/m°. Calculate the equivalent concentration in ppm at STP

jok3333 [9.3K]

Explanation:

It is known that for $NO_{2}$ , ppm present in 1 $mg/m^{3}$ are as follows.

1 $\frac{mg}{m^{3}}$ = 0.494 ppm

So, 150 $pg/m^{3}$ = $\frac{150}{1000} mg/m^{3}$

= 0.15 $mg/m^{3}$

Therefore, calculate the equivalent concentration in ppm as follows.

$0.15 \times 0.494 ppm$

= 0.074 ppm

Thus, we can conclude that the equivalent concentration in ppm at STP is 0.074 ppm.

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.
