Question

3.7 gram of a gas at 25 degree Celsius occupied the same volume as 0.184 gram of hydrogen and at 17 degree Celsius and at the same pressure what is the molecular weight of the gas ??.....

plzz any one solve this....

no smaping....

Answer 1

Here is ur answer, dear
_____________________⤵

➬ For Hydrogen,
━━━━━━━━━━━⬇

➧ W = 0.184g

➧ T = 290K at pressure & Volume

➧ PV
➾ 0.184 / 2× R ×290

➧ PV
➾ 0.184 / 2 × R × 290 ─── ➀

➬ For Gas,
━━━━━━━━⬇

➧ W = 3.7 g

➧ T = 298 K at Pressure & Volume

➧ PV
➾ 3.7 / m × R × 298

➧ PV
➾ 3.7 / m × R × 298 ─── ➁

▶By ➀ & ➁

➾ 0.84 / 2 × R×290
➾ 3.7 / m × R × 298
➾ m = 41.326 ...✔
