Determine the unknown property of a perfect gas

[thermo15378]

Homework Statement

a gas in 3-L container at a pressure of 300kpa and a temperature of 700 degrees celsius, and with a mass of .66 g.

Homework Equations

pv=nrt

The Attempt at a Solution

(300)(v)= (.00066 kg)(8.31)(191906 k)

= 3.51


im not sure what conversion needs to be done as the correct answer is found to be 1.401 kj/kg.K

From the information given and the answer you posted, you are to use PV= mRT to get 'R' for the gas.

In your calculation you found 'V' as 3.51 when they already gave you V=3 L.
