Question

A bacterial culture isolated from sewage produced 41.3 ml
of methane, CH4, at 31ºC and 753 mm Hg. What is the volume of this methane at STP?​

Answer 1

Answer:

=> Dear student,

At STP, P1 = 760 mm Hg

T1 = 273 K

V1 = ?

P2 = 753 mm Hg

V2 = 41.3 mL

T2 = 31 + 273 =304 K

According to Gas law,

P1V1/ T1 = P2V2/T2

V1 = 753 * 41.3 *273 / (304 * 760)

V1 = 36.7 mL

So the volume at STP = 36.7 mL
