The empirical formula is obtained by calculating the mole ratios of the atoms in the elements.
The number of moles =mass/ R.A.M
For hydrogen, no. of moles=8/1=8
For oxygen, no. Of moles=64/16=4
The tabular solution is attached.

Taking into account the definition of density, the density of the metal is 16.33 .
Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
<h3>Density of the metal in this case</h3>In this case, you know that:
- Mass= 34.3 g
- Volume= 2.1 mL
Replacing in the definition of density:
Solving:
<u><em>density= 16.33 </em></u>
In summary, the density of the metal is 16.33 .
