PV = nRT
P = 157 kPa = 157 × 10³ Pa
V = 265 ml = 0.265 l
T = 20°C = 293 K
m = 0.479 g
PV•M = mRT
M = (mRT)/(PV)
M = 0.479 g × 8.314 kPa.l/(mol.K) × 293 K / (157 kPa × 0.265 l)
M ≈ 28.04579 g/mol.
Hence, the Molar Mass of Dinitrogen or Nitrogen Gas is 28 g.
1.50 atm(760 mmHg/1 atm)=1140 mmHg
Answer:
Explanation:
The reaction we need to calculate:
1) 
We need the ClO in the products side, so we use the inverse of this reaction:
2) 
Now we need to combine this two:
The enthalpy of reaction:
I cannot come up with a reaction which you can convert directly from Al to H2O.
But you can convert from Al2O3 to H2O by adding HCL solvent.
