To calculate the number of moles of oxygen atoms in Vitamin C, we will use the formula that relates the number of atoms to moles, which is:
Oxygen:The eighth member of the periodic table having an O chemical symbol is defined as oxygen. When two atoms of this chemical element combine, then it forms a gas and this gas is known as oxygen gas. This is a smell less and color less gas, and very important for the life...

You have by this time most likely seen a few chemical formulas and some kind of representation of the associated molecular structures. For example, the simple molecule carbon dioxide, or CO2, can be represented as a carbon atom joined to two oxygen atoms by junctions called double bonds: O=...
Molar Mass of H2O:18.02 g/mol ElementSymbolAtomsMass % HydrogenH211.2% OxygenO188.8% Relate the moles of standard solution to the moles of unknown solution. Because this is a neutralization reaction, assume that the standard solution is the base (OH- ions). You calculated the moles of base...

Exploiting this rapidly growing technology, the Water Analysis Package (WAP) has been developed to enable the user to calculate geometrical parameters between water oxygen atoms and a user-specified region in a given protein or nucleic acid structure. In fact, there are few stand-alone programs (...
A given atom’s atomic number is always equal to its number of protons. Because oxygen has an atomic number of 8, the total number of protons in an oxygen atom is also 8. When describing which isotope an atom belongs to, the total number of neutrons is given to us for computation. At...
The molecular formula for glucose is \({{\rm{C}}_6}{{\rm{H}}_{12}}{{\rm{O}}_6}\). The molecular formula indicates the exact number of atoms in the molecule. The empirical formula expresses the smallest whole-number ratio of the atoms in the molecule. In the above case, the ...
