The empirical formula of the compound: [tex]Na_2CO_3[/tex]
Given:
A compound containing Na, C, and O is found to have 1. 06 mol Na, 0.528 mol C, and 1. 59 mol O.
To find:
The empirical formula of a compound.
Solution:
Let the empirical formula of the compound be =[tex]Na_xC_yO_z[/tex]
For empirical formula divide all the moles of elements by the least moles of an element.
[tex]x=\frac{1.06 mol}{ 0.528 mol}=2\\\\y=\frac{0.528 mol}{ 0.528 mol}=1\\\\z=\frac{1.59mol}{ 0.528 mol}=3\\\\[/tex]
The empirical formula of the compound: [tex]Na_2CO_3[/tex]
