Tiffany Perkins · Answer 1

It would be C. 9.56 L!

Lincoln Schultz · Answer 2

C) 9.56 L

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)
