Acompound that contains only carbon, hydrogen, and oxygen is 48.64% c and 8.16% h by mass. what is the empirical for- mula of this substance?

Mass % of carbon = 48.64 % (given)

Mass % of hydrogen = 8.16 % (given)

So, the mass percent of oxygen = %

Moles of each element is determined as:

Number of moles =

For

For

For

Dividing with the smallest mole value to calculate the mole ratio:

So, the formula is .

Converting the formula into whole number by multiplying with 2.

Hence, the empirical formula is

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
