 Initial Pressure in Pa for Trial 1:

       101071 / 1000 = 101.071 pascals

 

 Final Pressure in Pa for Trial 1:

 172743/ 1000 = 172.43 pascals 

 

Volume of flask:

 266 /106 = 0.000266 m3 

 

Volume hydrogen occupies (mL) :

 266-20=246 

 

Calculated moles of H2 (Trial 1) 

 7162 n/m2 x (0.000266 m3)

 (8.314 Nm/molK) x 296.2 K

 = .007913 mol 

 

 Atomic Weight:

 Trial 1: First

 0.170 g Me                                           

 0.00791 mol H2 x (2 mol Me/ 1 mol H2) 

 = 10.746 g/mol  

 

 Trial 1: Second

  0.170 g Me            

 0.00791 mol H2 x (1 mol Me/ 1 mol H2)  

 = 21.491 g/mol

 

 

 Trial 1: Third

     0.170 g Me                            

 .00791 mol H2 x (2 mol Me/ 3 mol H2) 

 = 32.258 g/mol
