Answer
Explanation
The given compound is Li₂O
What to fin:
The percent composition of oxygen in Li₂O.
Solution:
The first step is to calculate the total mass of Li₂O.
From the periodic table, the atomi weights of (Li = 6.941, O = 15.999)
Total mass of Li₂O = 2L + O = (2 x 6.941) + 15.999 = 13.882 + 15.999
Total mass of Li₂O = 29.881 gras
The mass of oxygen in Li₂O = 15.999 grams
The final step is to calculate the percent composition of oxygen in Li₂O.
