# Calculate the specific volume of natural gas under standard temperature and pressure?

(i.e. p=1013hPa, t=0C). Volume composition;

N2=0,05; CH4=0,95; MN=14[kg/kmol]; MC=12[kg/kmol]; MH=1[kg/kmol]

We have STP, and we know that 1 mole of gas occupies

V = 22.4 L = 0.0224 m³

molar mass of NG is

M = (0.05*2*14 + 0.95*(12 + 4*1)) g/mol = 16.6 g/mol

so

spec vol = V / m = 0.0224m³/mol / 0.0166kg/mol

spec vol = 1.35 m³/kg

at STP

Hope this helps!
