A student used a DCP solution (standardized to 9.94x10-4M) to analyze a sample of extract from 3.50g of solid food. The titration required 22.49mL of DCP. 91.75% of all the ascorbic acid in the food was collected in the extract. (MM Ascorbic Acid = 176.124 g/mol)

What mass of food (in grams) would be required to attain the RDA of ascorbic acid (60 mg)

PLEASE SHOW STEP BY STEP INSTRUCTION

the answer is definitely c.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
