190 g of water
60 g of KI
Explanation:
For concentration expressed in mass percentage of the solution we have the following formula:
concentration / 100 = mass of the dissolved / mass of the solution
mass of the dissolved KI = (concentration × mass of the solution) / 100
mass of the dissolved KI = (24 × 250) / 100 = 60 g
mass of the solution = mass of the water + mass of the dissolved KI
mass of the water = mass of the solution - mass of the dissolved KI
mass of the water = 250 - 60 = 190 g

Answer:
The answer is 98.07848. We assume you are converting between grams H2SO4 and mole. You can view more details on each measurement unit: This compound is also known as Sulfuric Acid. The SI base unit for amount of substance is the mole. 1 grams H2SO4 is equal to 0.010195916576195 mole.

8 moles H2SO3 to grams = 656.63264 grams
9 moles H2SO3 to grams = 738.71172 grams
10 moles H2SO3 to grams = 820.7908 grams
Here N H 4 O H { NH }_{ 4 }OH NH4OH is not a strong electrolyte because it doesn't dissociates completely.
Answer:
Li is more reactive then Be.
Explanation:
As you go to the farther left and down on the periodic table, the higher that element reactivity is.
Answer:
The most state has the high volume is the gas state.
So here the answer is vaporization!!!!
Explanation:
The most state has the high volume is the gas state.
So here the answer is between vaporization and sublimation???
and when the sublimation is: the change of the material from the solid state to the gas state directly without pass to liquid state from the solid first then to the gas
and the vaporization is : The change of the material from the liquid state to the gas state by heating Ex: water vaporize at 100°
here, the answer is sublimation because the difference of volume which resulted from this process is more than the volume resulted from vaporization.
