What is the sum of mass percent composition?
The molar mass is the sum of the masses of all the atoms in one mole of the compound. The sum of all the mass percentages should add up to 100%.

What is the mole percentage composition of carbon dioxide?
Mole percentage composition is a mole percentage of each element in a compound. We only need the molecular formula of a compound to determine it. The molecular formula of carbon dioxide is CO 2. So, one mole of CO 2 contains one mole of carbon and two moles of oxygen. Thus, the total number of moles is nC + nO = 1 + 2 = 3 mol.

How many bonds does each carbon oxygen and hydrogen atom form in glucose?
The carbon atoms in the glucose ring each have four covalent bonds. The best, or optimum angle, between all these bonds is 109.5o, which results in a perfect tetrahedron. If, for any reason, these bonds are forced into greater, or smaller angles then the molecule will be strained or stressed, and be much less stable.
What is percent composition?
Percent composition refers to the percentage of an element in a given compound. As we all know, all chemical compounds are made up of different elements. In the composition of a compound, different elements are added in different ratios. Thus, we find the percent composition of a compound to know how much amount of an element or all the elements is present in the sample.
