In the space station, a 2 mole sample of neon is kept at 1.in the space station, a 2 mole sample of neon is kept at 1.0atm and 50k. what is the true volume of the gas? the molar volume correction factor "b" for neon is 0.01709 l/mol and r = 0.08206 l atm/mole k. express volume in liters.

Answer : The volume of the gas is, 8.24018 L

Solution : Given,

Moles of gas = 2 moles

Pressure of gas = 1 atm

Temperature of gas = 50 K

Molar volume correction factor, b = 0.01709 L/mole

Gas constant, R = 0.08206 L atm/mole K

Formula used for real gas :

where,

P = pressure of gas

V = volume of gas

T = temperature of gas

R= gas constant

n = number of moles of gas

b = molar volume correction factor

a = pressure correction factor

The value of 'a' is zero

Now put all the given values in this formula, we get the volume of gas.

Therefore, the volume of the gas is, 8.24018 L

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
