What pressure is required to compress 156.0 liters of air at 2.00 atmosphere into a cylinder
garik1379 [7]

Answer:

option B.

Explanation:

Given,

V₁ = 156 L

P₁ =2 atm

Now, in the cylinder

P₂ = ?

V₂ = 36

Using relation between pressure and volume

\dfrac{P_1}{V_2}=\dfrac{P_2}{V_1}

\dfrac{2}{36}=\dfrac{P_2}{156}

P_2 = 8.67\ atm

Hence,  pressure is equal to 8.67 atm.

Hence, the correct answer is option B.

Given

Mass of NO - 824 g

Molar mass of NO - 30.01g/mol

No of moles of NO = Given mass/Molar mass

No of moles of NO = 824/30.01= 27.45 mole

Hence 27.5 moles of NO are formed!
