Answer:
0.022 moles of ammonium phosphate produced by the reaction of 0.065mol of ammonia.
Explanation:
Moles of ammonia = 0.065 moles
According to reaction, 3 moles of ammonia gives 1 mole of ammonium phosphate ,then 0.065b moles of ammonia will give:
0.022 moles of ammonium phosphate produced by the reaction of 0.065mol of ammonia.
Answer:
H₂: 0.48, N₂: 0.43; Ar: 0.09
Explanation:
First of all, sum all the pressures to know the total pressure in the mixture.
434 Torr + 389.9 Torr + 77.9 Torr = 901.8 Torr
Mole fraction = Pressure gas / Total Pressure
Mole Fraction H₂: 434 Torr /901.8 Torr = 0.48
Mole Fraction N₂: 389.9 /901.8 Torr =0.43
Mole Fraction Ar: 77.9 /901.8 Torr = 0.09
Remember: <u>SUM OF MOLE FRACTION = 1</u>
The number of moles of gas present are 0.0054
<u>Explanation:</u>
Given-
Temperature, T = 100°C = 100 + 273 = 373K
Volume, V = 0.044L
Pressure, P = 3.81 atm
Moles of gas, n = ?
We know,
PV = nRT
R = 0.082 L.atm.K⁻¹.mol⁻¹
n = PV/RT
n = (3.81)(0.044)/(0.082)(373)
n = 0.0054 moles
Therefore, number of moles of gas present are 0.0054
