How many moles are in 0.98 grams of Potassium chloride?
About 0.013
How many moles in 449 g of potassium?
Potassium (chemical symbol K) has atomic number 39.1. Amount of K in 449g sample = 449/39.1 = 11.5mol There are 11.5 moles of potassium in a 449g sample.
How many moles of KCl will be formed from 0.440 moles of KClO3?
2 KClO3 ------ 2KCl + 3O2 so 2 moles of KClO3 produces two mole of KCl. Therefore 0.440 moles of potassium chlorate will produce 0.44 moles of KCl - potassium chloride.
How many chloride ions are in a sample of salt that contains 2 moles of KCl?
1.20442 x 1024 chloride ions
How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose into potassium chloride and oxygen?
You have2KClO3 ==> 2KCl + 3O2 as the balanced equation 25 g KClO3 x 1 mole/123 g = 0.20 moles moles KCl formed = 0.20 moles KClO3 x 2 moles KCl/2 moles KClO3 = 0.20 moles KCl formed grams KCl = 0.20 moles x 74.5 g/mole = 14.9 g = 15 grams of KCl formed
How many moles in 284 grams of potassium?
Potassium has atomic number 39.1.Amount of K in 284g sample = 284/39.1 = 7.26molThere are 7.26 moles of potassium in a 284g sample.

How many chloride ions are in a sample of salt that contains 2 moles of MgCl2?
2.4088 x 1024 chloride ions
How many chloride ions are in a sample of salt that contains 2 moles of KCl?
1.20442 x 1024 chloride ions
How many moles of potassium chloride are formed from 7 mol of HCl?
7: Molecules of HCl and KCl have the same number, 1, or chlorine atoms per mole; therefore, if HCl reacts completely with potassium, the same number of moles of potassium chloride as the number of moles of hydrogen chloride present will be formed. (For an ionic compound such as KCl, the term "formula unit" is preferable to "mole", but the mathematical consequences are the same.)
What is the molarity of a solutions where 4.00 moles of potassium chloride is dissolved in 2.00 L OF SOLUTIONS?
4.00 moles/2.00 L = 2.00 moles/L = 2.00 M

How many moles of potassium are in 156.4 g of potassium?
Molecular weight of potassium (K): 39.1 g/mole...Just divide 156 by the molecular weight to get moles:156/39.1 = 3.99 moles K
How many moles in 0.630gNaCl?
The formula mass of sodium chloride is 23.0 + 35.5 = 58.5 Amount of sodium chloride in a 0.630g pure sample = 0.0108mol
In the reaction MgCI2 plus 2KOH Mg(OH)2 plus 2KCI if 3 moles MgCI2 are added to 4 moles KOH what determines how much Mg(OH)2 is made?
The potassium hydroxide is what we call the limiting reactant. 4 moles of potassium hydroxide react with 2 moles of magnesium chloride. The third mole of magnesium chloride is in excess and has no effect.
