Explanation:
Moles of phosphorus pentachloride present initially = 2.5 mol
Moles of phosphorus trichloride at equilibrium = 0.338 mol
Initially
2.5 mol 0 0
At equilibrium:
(2.5 - x) mol x x
So, from above, the moles of phosphorus trichloride at equilibrium , x= 0.338 mol
Mass of 0.338 moles of phosphorus trichloride at equilibrium:
= 0.338 mol × 137.5 g/mol = 46.475 g
Moles of phosphorus pentachloride present at equilibrium :
= (2.5 - 0.338) mol = 2.162 mol
Mass of 2.162 moles of phosphorus pentachloride at equilibrium:
= 2.162 mol × 208.5 g/mol = 450.777 g
Moles of chloride gas present at equilibrium : 0.338 mol
Mass of 0.338 moles of chloride gas at equilibrium:
= 0.338 mol × 71 g/mol = 23.998 g
Answer:
Plausible structure has been given below
Explanation:
- Molar mass of
is 44 g/mol and molar mass of
is 18 g/mol
- Number of mole = (mass/molar mass)
4.04 g of =
= 0.0918 moles of
1 mol of contains 1 mol of C atom
So, 0.0918 moles of contains 0.0918 moles of C atom
1.24 g of =
= 0.0689 moles of
1 mol of contain 2 moles of H atom
So, 0.0689 moles of contain
of
or 0.138 moles of
Moles of C : moles of H = 0.0918 : 0.138 = 2 : 3
Empirical formula of hydrocarbon is
So, molecular formula of one of it's analog is
Plausible structure of has been given below.
