Two moles because one moles would be 6.02×10 23 atoms 2 moles would equal twice that number of atoms
Answer:
u = 0.176 m/x
Explanation:
∴ n O2 = 1 mol
∴ mass O2 = 1 mol * 32 g/mol = 32 g
∴ T = 60°C = 333 K
∴ P = 5 bar
⇒ V = RTn/P = (83.14 bar.cm³/mol.K)*(333 K)*(1 mol))/(5 bar)
⇒ V = 5537.124 cm³
∴ d = 20cm
⇒ A = (1/4π)*d² = 314.16 cm²
velocity of the gas (m/x):
- u = m / ρ*A
- let time (t) = x sec
∴ ρ = 32 g / 5537.124 cm³ = 5.78 E-3 g/cm³
∴ mass flow rate (m) = 32g / x
⇒ u = (32 g/x) / (( 5.78 E-3 g/cm³)*(314.16cm²))
⇒ u = 17.625 cm/x * ( m/100cm) = 0.176 m/x
From the Dalton's law of partial pressures, the pressure of the hydrogen gas is 91.83 kPa.
<h3>What is partial pressure?</h3>
In a mixture of gases, the total pressure is the sum of the pressures of the individual gases in the mixture according to the Dalton's law of partial pressures.
In this case, the partial pressure of the hydrogen gas is Phydrogen, the partial pressure of water is Pwater and the total pressure is PT.
Hence;
Phydrogen = PT - Pwater
95 - 3.17 = 91.83 kPa
