<p>Stoichiometry is <span style="font-weight:bold">a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data</span>.</p><p>The term is <span style="font-weight:bold">derived from the Greek words stoicheion, meaning element, and metron, meaing measure</span>.</p><p><span style="font-weight:bold">Almost all stoichiometric problems can be solved in just four simple steps:</span></p><ol><li>Balance the equation.</li><li>Convert units of a given substance to moles.</li><li>Using the mole ratio, calculate the moles of substance yielded by the reaction.</li><li>Convert moles of wanted substance to desired units.</li></ol><p>What are basic laws of stoichiometry?</p><p>It states that “Mass is neither created nor destroyed in a chemical reaction or The total mass of reactant is equal to the total mass of product in a chemical reaction”.</p><p> </p>
