What conversion factor is present in almost all stoichiometry calculations?

Answer;

Molar mass

Explanation;Stoichiometry involves the study of quantitative relationships between the amounts of reactants used and products formed by a chemical reaction. A conversion factor is a ratio of coefficients found in a balanced reaction, which can be used to inter-convert the amount of products and reactants.Molar ratios, or conversion factors, identify the number of moles of each reactant needed to form a certain number of moles of each product.

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.
