At 32°C and 205 kpa gauge. The specific weight of a certain gas was 13.7 `"N"/"m"^3`. Determine the gas constant of this gas.

T= 32 + 273 = 305 K

P absolute = 205 + 101.325 = 306.325 kPa

Specific weight = 13.7 N/m3

Mass density = 13.7/9.81 = 1.397 kg/m3

R= P/(mass density × T)

R= 306,325 Pa / (1.397 kg/m3 × 305 K)

R= 718.93 J/kg.K
