3.2g of oxygen (atomic wei

Answer 1

Answer:

tttttttttttttttttttt

Answer 2

Answer:

   

You are dealing with diatomic oxygen ( molar mass 32g/mol ) and diatomic hydrogen ( 2g/mol )

Mol O2 in flask = 3.2/32 = 0.1 mol  

Mol H2 in flask = 0.2/2 = 0.1 mol H2  

Total moles = 0.2mol  

Calculate pressure using gas equation:  

PV = nRT

P * 1.12 = 0.2*0.082057*273  

P = 4.480/1.12  

P = 4.000 atm  

Pressure = 4atm
