A tank has 1.90 mols of Nz gas under a pressure of 4.972 atm at 31.8 °C.
Calculate the volume of the tank.
A) 4.64 L
B) 11.76 L
C) 9.56 L
D) 3.76 L

C) 9.56 L

Explanation:

Equation for the ideal gas:

PV=nRT

so, V= (nRT)/P1

Here,

n=1.90 moles

R= .0821 Latmmol-1k-1

T=31.8+273= 304.8 K     [T(un kelvin scale)=t(in celcius scale)+273]

P= 4.972 atm

Now from eq 1 we can determine the volume of the gas or tank V, which is 9.56 L(option C)

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
