Answer:
C. 0.04 moles per cubic decimeter.
Explanation:
The molar mass of the Iodine is 253.809 grams per mole and a cubic decimeter equals 1000 cubic centimeters. The concentration of Iodine (), measured in moles per cubic decimeter, can be determined by the following formula:
(1)
Where:
- Mass of iodine, measured in grams.
- Molar mass of iodine, measured in grams per mol.
- Volume of solution, measured in cubic decimeters.
If we know that , and , then the concentration of iodine in a solution is:
Hence, the correct answer is C.
Answer:
Temperature
Explanation:
temperatures below 0 degrees celsius will turn water into ice
Temperatures 1 to 99 degrees celsius is water in liquid form
Temperatures of over 100 degrees celsius liquid turns into gas
