Question

50 cm3 of hydrogen is collected over water at 27 degree celcius and 750 mm pressure . calculate the volume of dry gas at S.T.P the water vapour pressure at 27 degree celcius is 14mm Hg....


help me plsss .ಥ‿ಥ ಥ‿ಥ​

Answer 1

Answer:

Explanation:

45.58 cm  3

Given that

P1  =750mmHg−14mmHg=736mmHg

V1=50cm3  ,T1=17  

0C=290K

P2=760mmHg

V2=?cm3  ,T2=0C=273K

Hence the Gas equation

​290/736×50 =273/760×v2

∴V2​=  290×760/736×50×273

V2​=45.58 cm3

 

Thus, the volume of dry gas at STP is 45.58 cm  3
