4. A 6.9 L volume of ideal neon gas (monatomic) is at a pressure of 2.5 atmospheres and a temperature of 400k. The atomic mass of neon is 20.2 g/mol. In this situation, the temperature of the gas is increased to 500 and the volume is increased to 8.9 L. The final pressure of the gas, in atmospheres, is closest to:

A)2.2                       

B)2.4

C)2.9                       

D)3.1

E)2.7

Explanation / Answer

1

P*pi*D^(2)/4=1.88*10^(6)

P=26.59*10^(6)

P=1.0123*10^(5)+p*g*H

H=2703.6m=2.70Km

so option(a)
