Calculate the pressure in a mixture of 8g of O_(2)(g)and 4 g of H_(2)(

1.	Calculate the pressure in a mixture of 8g of O_(2)(g)and 4 g of H_(2)(g) confined in a vessel of1 dm^(3) "at" 27^(@)C (R=0*083 dm^(3) "bar" K^(-1) "mol"^(-1))
Answer» <P> Solution :No. of moles `=("mass")/("moleculear mass")` `NO_(2)=(8)/(32)=025 "" NH_(2)=(4)/(2)` `n_("TOTAL") =025+2=225, T=27+273=300K` `PV= nRT :. P(nRT)/(v)=(225xx0083xx300)/(1)` `:. P=025` bar
