- Volume to molecules. A human red blood cell has an average volume of about 90 femtoliters. Assuming 64% (use the conversion factor 64 g of water = 100 g of cell) of this volume is water, how many molecules of water are present in the average red blood cell? Use the density of water (1.0 g/mL) and the percentage of water to find the mass of water in grams (0) (ii) Use the mass of the water (i), its molar mass, and Avogadro's number to calculate the number of water molecules

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
