Explanation / Answer

Question-1

use ideal gas equation PV = n RT

where P is the pressure

V is the volume

n is the number of moles

R is the universal gas constant

T is temperature in K

now, density = mass/ volume

P V = m/M RT

PM = m /v RT

from this m/v is density or d

So we can write, PM = dRT

where, M is the molar mass

d = P M / RT

= (1.1 atm x 17g) / (0.0821 x 318 K)

= 0.716

Question-2

Dalton’s law connect between Total pressure and partial pressure, Statement “the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of the component gases”

Question-3

GayLussac’s Law states that at constant volume, pressure of a fixed amount of a gas is directly proportional to the temperature.

Mathematically,

P1/T1 = P2/T2

Or P1 x T2 = P2 x T1

here T1 = 300 K and P1 = 10 atm

T2= ? And P2 = 100 atm

Therefore, 10 x T2 = 100 x 300

T2 = (100 x 300) / 10 = 3000 K

Question-4

incorrect statement about a gas?

All gases are compressible, or the 4th statement is incorrect or not true, that is “it cannot be compressed”

Question-5

identify the Noble gas?

PM = d RT

0.0365atm x M = 1.78g/L x 0.082L atm K /mol x 10 K

therefore Molar mass or M = (1.78 x 0.082 x 10 ) / 0.0365 = 39.9890

or the molecular mass of Argon is 39.948

So the noble gas asked in question is Ar.

Question-6

Avogadro Law (Volume – no. of moles or Amount Relationship)

It states that equal volumes of all gases under the same conditions of temperature and pressure contain equal number of moles or molecules. This means that at constant temperature and pressure, the volume of a gas is directly proportional to its number of moles (n) or molecules (N).

i.e.,

V proportional to n, n is the number of moles and V is the volume

i hope you got the answer, thank you
