Answer:
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
