Acompound has an empirical formula of ch2o. an independent analysis gave a value of 150.13 g for its molar mass. what is the molecular formula of the compound?

Explanation:

The empirical formula of the compound =

Molecular formulas is the actual number of atoms of each element in the compound while empirical formulas is the simplest or reduced ratio of the elements in the compound.

Thus,  

Molecular mass = n × Empirical mass

Where, n is any positive number from 1, 2, 3...

Mass from the Empirical formula = 1×12 + 2×1 + 16= 30 g/mol

Molar mass = 150.13 g/mol

So,  

Molecular mass = n × Empirical mass

150.13 = n × 30

⇒ n = 5

The formula of the compound =

the ratio of the conjugate base to the acid required to attain the desired ph.
