Plzzz i dont get this you discover a chemical reaction that produces 2 moles of valuable propane for every 9 moles of carbon supplied. essentially, this is an exchange rate of 2 moles of propane for every 9 moles of carbon. if you have 1.3 moles of carbon, how many moles of propane can you produce using this reaction?

Chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. One significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. In order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.

i think its 100

i hope this !
