Answer:

H₂O

Step-by-step explanation:

Given parameters:

Mass of hydrogen = 0.6g

Mass of oxygen = 4.8g

Unknown:

Empirical formula of the water = ?

Solution:

The empirical formula is the simplest formula of a compound.

Elements Hydrogen Oxygen

Mass 0.6 4.8

Molar mass 1 16

Number of

moles 0.6/1 4.8/16

0.6 0.3

Divide by the

smallest 0.6/0.3 0.3/0.3

2 1

The empirical formula is H₂O
