Answer:
1.25 M
Explanation:
Step 1: Given data
Mass of KI (solute): 20.68 g
Volume of the solution: 100 mL (0.100 L)
Step 2: Calculate the moles of solute
The molar mass of KI is 166.00 g/mol.
20.68 g × 1 mol/166.00 g = 0.1246 mol
Step 3: Calculate the molar concentration of KI
Molarity is equal to the moles of solute divided by the liters of solution.
M = 0.1246 mol/0.100 L= 1.25 M
Answer:DISADVANTAGES:
The main disadvantages are the expensive and age of enormous amounts of profoundly radioactive waste.
ADVANTAGES:Radiation treatment for cancer and examines the metabolic state without and significant harm to patients.
Explanation:
Don't you think that element is ferrous i mean iron.
Answer:
Molecules of matter such as liquid, gas and solid still move even if the energy is transferred because it isn't a hundred percent. There is still energy and the time it took to transfer that said energy would have changed its state of matter.
Explanation:
Solid -the molecules are tight together. (touching)
Liquid - the molecules are close but not touching about mid way(not to far not to close)
Gas- the molecules in gasses are far apart.
It almost always goes from solid to liquid to gas. but in extreme conditions it could be different.
