Given

#"The molar sp.heat at constant pressure "( C_p )= 35100/1000JK^-1mol^-1=35.1JK^-1mol^-1#

#gamma=C_p/C_v=1.31#
#"Where " C_v->"molar heat capacity at constant volume"#

#C_v=C_p/gamma=35.1/1.31JK^-1mol^-1#

We know
#C_p-C_v=R->"Universal gas constant"#

#:.R=35.1-35.1/1.31=(35.1xx0.31)/1.31JK^-1mol^-1#

#~~8.3061JK^-1mol^-1#
