Question

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

Answer 1

C) 9.56 L

Step-by-step explanation:

Equation for the ideal gas:

PV=nRT

so, V= (nRT)/P......1

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)

Answer 2

it would be C. 9.56 L !
