Answer:
Analysis of a sample of a compound composed of carbon, hydrogen, and oxygen shows that the sample contains 18.80 g of C, 2.367 g of H, and 25.04 g of O.
The properties of the compound suggest that the molar mass should be 59.04 g/mol.
How many carbon atoms are there in one molecule of the compound?
Explanation:
Empirical formula mass is
[tex](12g/mol*2)+(1.0g/mol*3)+(16.0g/mol*2)\\=59.0g/mol\\[/tex]
Empirical formula mass =molecular formula mass
Hence,
empirical formula is same as molecular formula.
That is --- [tex]C_2H_3O_2[/tex].
So, the molecule has two carbon atoms in one molecule of the compound.
