Factors such as age, activity level and health make a difference in what and how much a cat should eat. Cats require taurine, an essential amino acid, for heart and eye health. The food you choose should be balanced for the life stage of your cat or kitten. Properly balanced foods will contain taurine.
Magnesium Chloride is an inorganic salt, which has the chemical formula of MgCl2 and molecular weight 95.210 g/mol. Predominantly magnesium chloride exists as various hydrates, particularly hexahydrate MgCl2 *6H2O having the molecular weight of 203.301 g/mol.
The mass of potassium chloride is 3.8 g. Take the balanced chemical equation 2KClO_3 -> 2KCl + 3O_2 Look at the mole ratio you have between potassium chlorate and potassium chloride; what you will see is that every 2 moles of potassium chlorate will produce 2 moles of potassium chloride, i.e. you have a 1:1 mole ratio between the two compounds.
