Answer:
Cost to supply enough vanillin is 
Explanation:
Threshold limit of vanillin in air is 
per litre means there should be of vanillin in 1L of air to detect aroma of vanillin.
So, 
So amount of vanillin should be present to detect = 
As cost of 50 g vanillin is 
therefore cost of vanillin = 
B, more kinetic energy means more collisions and thus more reactions according to collision theory.
Answer:
426 mg = 4.26 x 10² mg
Explanation:
1 cup = 237.6 mL x 1 L/1000 mL = 0.2376 L
We divide the liters of milk the student drinks into the volume in liters of a cup to calculate the number of cups the student drinks per day:
number of cups per day = 0.318 L/0.2376 L = 1.34 cup
Now, we multiply the number of cups by the amount of calcium that a cup of milk has:
amount of calcium = 1.34 cup x 318 mg = 426 mg = 4.26 x 10² mg
Therefore, the student gets 426 mg (or 4.26 x 10² mg) of calcium in one day.
