Balanced equation is given by

\\ \rm\Rrightarrow 4Fe+3O_2\longrightarrow 2Fe_2O_3

On both sides

  • Fe=4
  • O=6

Hence balanced

Now

  • 3mols of O_2 produces 2 mol Fe_2O_3
  • 1 mol O_2 produces 2/3=0.6mol Fe_2O_3

Moles of O_2:-

  • 17/32= 0.5mol

Moles of Fe_2O_3;

  • 0.5(0.6)=0.3mol

Mass of Fe_2O_3:-

  • Moles (Molar mass)
  • 159.7(0.3)=47.91g

A sample of nitrogen gas is stored in a 489.6 mL flask at 108 kPa and 10.0°C. The gas is transferred to a 750.0 mL flask at 28.7
Wewaii [24]

Answer:

P2= 125.26 Kpa

Explanation:

V1= 489.6 ml=0.4896L

V2= 750 ml= 0.750L

V1= 180 KPa= 180000 Pa

P2= ?

T1= 10 = 10 + 273.15 = 283.15K

T2= 28.7+273.15= 301.85K

180000Pa* 0.4896L/ 283.15K * 301.85K/0.75L

P2= 12526.28553

P2= 125.26 KPa
