When the mass of lead II iodide precipitate is measured how is it converted into moles of lead II iodide?
Lerichardson
you calculate the number of moles by working out the gram formula mass of Lead II iodide, which should be 461.03 g/mol, and divide that by the measured ammound of substance you have in grams. That will give you the number of moles of substance you have.

What is the molarity of a solution prepared by dissolving 2.41 g of potassium iodide KI in 100 mL of water?
Find moles potassium iodide first.2.41 grams KI (1 mole KI/166 grams) = 0.01452 moles KIMolarity = moles of solute/Liters of solution ( 100 ml = 0.1 Liters )Molarity = 0.01452 moles KI/0.1 Liters= 0.145 M KI solution================
How many moles in 135 g of iodine?

What is the balanced equation when iodine reacts with sodium hydroxide?
6NaOH + 3I2 = 5NaI + NaIO3 + 3H2O Six moles of sodium hydroxide and three moles of diatomic iodine yield five moles of sodium iodide, one mole of sodium iodate, and three moles of water. Cheers!
How many moles of iodine are produced from 8.00 moles of chlorine?
You cannot produce any Iodine from chlorine, because chlorine (Cl2, gas) is an element, hence it does not contain any Iodine (I2, solid with purple vapor). However when 8.00 moles Cl2 react with excess (>16) moles potassium Iodide (KI) then also 8.00 moles of Iodine are produced, not FROM but BY MEANS OF chlorine. Cl2 + 2KI --> 2 KCl + I2
How many grams are in 0.02 moles of beryllium iodide moles of beryllium iodide?
0.02 moles of beryllium iodide is equal to 5,256 g.
How many grams are in 0.02 moles of beryllium iodide?
0.02 moles of beryllium diiodide = 5,256 grams
How are moles converted into number of particles?
The moles are converted into a number of particles by multiplying 6.02 by 10(with the power of 23)
How many moles of iodine are needed to react with 5 moles of potassium to create potassium iodide?
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
HOW TO prepare 0.1 n iodide solution in 500 ml water?
0.1 N iodide would be 0.1 moles of the iodide salt (e.g. KI) per liter of solution. For 500 ml, you would need 0.05 moles of the iodide salt. You need to state the salt (KI, NaI, LiI, etc.) in order to determine the actual mass required.

How many moles of potassium iodide are there in 50 grams?
For this you need the atomic (molecular) mass of KCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. KCl= 74.6 grams50.0 grams KCl / (74.6 grams) = .670 moles KCl
How can the stoichiometry be determined for a reaction that forms a gas instead of a precipitate?
If a reaction produces a gas instead of a precipitate, the volume of the evolved gas can be measured. With the volume, temperature, and pressure of the gas known, the number of evolved moles of gas can be calculated. If the pressure is fairly low, the ideal gas law should give an adequate method to calculate the number of moles: n = PV/RT If the number of moles of the reactants and any other products are know, the stoichiometry should be fairly straightforward to calculate - unless there are multiple reactions occurring.

How many moles of hydrogen iodide are produced from 1 mole of iodine?
The balanced equation for the reaction between Iodine and Hydrogen is: H2 + I2 --> 2HI The ratio of I2 to HI is 1:2 Therefore 1 mole of Iodine can form a maximum of 2 moles of Hydrogen Iodide
What is 2.20 moles of sn?
