Dear student ,
 
Given :  V= 34.05 mL = 34.05 * 10-3 L
             T =5460C  = 819K
             P= 0.1 bar = 0.1 atm ( approx)
             w = 0.0625 g 
 
Now, we will use the fomula :           PV= nRT
                                                          PV=( w/ Molar mass ) RT
 
   use R = 0.0821 atmLmol-1K-1
keeping all the values in the above formula you will get the value of molar mass.
