Answer:
The structure of the CO32– ion can be described in the Lewis formulation by these structures below. This means that a) two carbon-to-oxygen bonds are single bonds; the third is a double bond.
The number of grams of oxygen present in a sample of this compound that contains 40.00 grams of S = 29.9g of oxygen
<h3>Calculation of quantity of Oxygen</h3>
The compound contains the following:
sulphur = 57.20%
Oxygen= 100 - 57.20 = 42.80%
If 57.20% of the sample contains 40g of sulphur then 42.80% of the sample will contain X.
Make X the subject of formula,
X = 42.8 × 40/57.20
X= 1712/57.20
X= 29.9g of oxygen
