Question

Find the vapour density of carbon dioxide .( c= 12 , O = 16 )
give full solution...

Answer 1

$\huge \bf{ \fbox{\blue{answer}}}$

$\red{vapour \: density = \frac{molecular \: mass}{2} }$

Molecular Mass of CO2 = 1*12 + 2*16

= 44

So, Vapour Density = 44/2

$\huge \fbox{ \pink{Vapour \: Density = 22}}$

$\huge \mathfrak{ \red{thanks}}$

Answer 2

$\huge\bf\pink{\mid{\overline{\underline{Your\: Answer}}}\mid}$

${\bold{\red{\huge{22}}}}$

step-by-step explanation:

♣ Vapour density

✍️ Vapour density is the density of a vapour in relation to that of hydrogen.

✍️ It may be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen.

✍️ vapour density = mass of n molecules of gas / mass of n molecules of hydrogen. 

✍️ The density of any gas (or vapor) depends on the pressure where it is found.

✍️ This is due to a smaller number of gas phase atoms or molecules being present per unit volume.

✍️  Temperature has an effect on pressure, but this is due to increased velocity of gasphase atoms or molecules with increased temperature.

✍️ Now,

we have to find vapour density of $CO_2$

molecular mass of $CO_2$ = 12 + 2×16

= 12 + 32

= 44

Now,

we know that,

Vapour density, V.D = Molecular mass/2

=> V.D = 44/2

=> V.D = 22
