Answer #1

What is the density (in g/L) of hydrogen gas at 20.0 degrees C and a pressure of 1655 psi?

T= 273 +20=293K

P= 1655psi

1 atm = 14.7 psi

      ?       =1655psi

P= 112.58atm

PV= n RT

PV = wRT/M

P = (W/V) RT/M

P= d RT/M

denstity (d)= M P /RT

                  = (2 x 112.58) /(0.0821x293 )

                  = 9.36g/ml
