A lone oxygen atom has 6 electrons in its outer shell which is not very stable, whereas as full octet (8 outer shell electrons) is stable. In order to achieve this two oxygen atoms will share 4 electrons, each contributing 2 electrons. Since these electrons exist within the orbitals of both atoms, to oxygen atoms essentially achieve a full octet.

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.

Calculate the concentration of hydrochloric acid if 225.0 mL of this acid is neutralized by 120.0 mL of 2.0m sodium hydroxide A.

timurjin [86]

M1V1 = M2V2
225M1 = (2)(120)
225M1 = 240
M1 = 240/225 = 1.066 M C
