Problem: Calculate the mass percent composition of each constituent element of carbon dioxide.

FREE Expert Solution

Assume 100 g sample.

The chemical formula of carbon dioxide s CO2.

Step 1. Compute for the mass of each element for every 100 sample.

mass C=100 g CO2 (1 mol CO244.01 g CO2)(1 mol C1 mol CO2)(12.01 g C1 mol C)=27.29 g C

mass O=100 g CO2(1 mol CO244.01 g CO2)(2 mol O1 mol CO2)(16.00 g O1 mol O)=72.71 g O

Step 2. Calculate percent composition.
