The ratio of sugar to flour in the recipe is 1 to 2. If you use 5 cups of sugar, how much flour do
you need to use?

10 flour

Step-by-step explanation:

          1:2

         5:x     all you have to do is multiply by 2, sense the ratio is 1:2, flour will always be 2 times greater than sugar. so the answer is 5 x 2 =10

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.
