No
Explanation:
Let us examine this problem carefully:
Given compound is N₂O
Molecular mass = 88g
Now,
The empirical formula is the simplest formula of a compound.
The molecular formula is the true formula of the compound that shows that actual ratios of the atoms in a compound.
To find if they both have the same molecular and empirical formula, they must have the same molecular mass.
For N₂O;
Molecular mass = 2(14) + 16 = 44g/mole
But the true and given molecular formula of the compound is 88g/mole
This shows that the compound given is the empirical formula of the compound.
Molecular formula:
molecular mass of empirical formula x n = molecular mass of molecular formula
n = = 2
Molecular formula of compound = 2(N₂O) = N₄O₂
Therefore the empirical and molecular formulas are not the same
The total pressure of the mixture is 65.5 kPa.
According to Dalton's Law of Partial Pressure,
The partial pressure of gas = Mole fraction of gas × Total pressure
Total Pressure = Sum of all the gases partial pressures
The number of moles of methane is,
= 0.021 mols
The moles of methane are 0.021 mols.
The number of moles of the argon,
= 0.003 mols
The number of moles of argon is 0.003 mols.
The number of moles of nitrogen is,
= 0.010 mols
The number of moles of nitrogen is 0.010 mols.
The total number of moles is,
= 0.021 + 0.003 + 0.010
= 0.034 mols
= 0.29
= 65.5 kPa
Therefore, the total pressure of the mixture is 65.5 kPa.
