Explanation:
molecular collisions. reactant particles must collide with one another before any reaction can occur.
activation energy. colliding particles must possess a certain minimum total amount of energy if the collision is result in reaction.
Concentration Definition. In chemistry, concentration refers to the amount of a substance per defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration usually is expressed in terms of mass per unit volume.
Concentration = no of moles of solute/solvent
Answer:
533.33 mg quinine
Explanation:
First we<u> calculate the concentration of the diluted sample</u>, using the values obtained by the standard:
- 288 * 100 ppm / 180 = 160 ppm
Now we use the dilution factors to <u>calculate the concentration of quinine in the original sample</u>:
- 160 ppm * 100mL/15mL = 1066.67 ppm
ppm can be defined as <u>mg of quinine</u>/L solvent:
500 mL solution ⇒ 500/1000 = 0.5 L
- 1066.67 ppm * 0.5L = 533.33 mg quinine
