How many particles does potassium chloride have?
The formula unit of potassium chloride (KCl) has two atoms.
How many moles of KCl in 0.90M KCl?
The answer is of course 0,9 M.
How many moles of KCl are contained in 1.7L of a 0.83M KCl solution?
moles KCL = ( M solution ) ( L of solution )moles KCl = ( 0.83 mol KCl / L ) ( 1.7 L ) = 1.41 moles KCl
How many moles of KCl are contained in 0.635L of 2.2M KCl?
moles KCl = ( M solution ) ( V solution in L )moles KCl = ( 2.2 mol KCl / L solution ) ( 0.635 L of solution )moles KCl = 1.397 moles KCl
How many moles are in 12.57 grams of KC1?
12.57 grams KCl (1mol KCl/74.55g ) = 0.1686 moles
How many atoms in total are in a potassium chloride molecule?
The potassium chloride formula unit (KCl) contain two atoms (K and Cl). Potassium chloride is an ionic compound and therefore does not have true molecules at all.
How many atoms are in the compound KCI?
two elements and two atoms (potassium and chlorine)In one molecule of KCl, there are two elements (potassium and chlorine).The molecular weight of KCl is 74.55 g / mol.So, 74.55 g of KCl will contain 6.023 x 1023 molecules or 12.046 x 1023 atoms.
How many elements and atoms are in KCl?

Represents a compound -how are the elements in the compound and the ratio of atoms?
Example: potassium chloride, KCl Elements in the molecule: potassium and chloride Ratio potassium/chlorine: 1
How many atoms of K in 2.77g of KCl?
2.77 g KCl * x moles KCl/ 74.5 g/mol 0.0372 mol KCl * 1 mol K/ 1 mol Cl = 0.0372 mol K 0.0372 mol K * 6.02*10^23 2.24*10^22 atoms K
How many particles does potassium chloride have?
The formula unit of potassium chloride (KCl) has two atoms.
How many molecules of KF are formed when 2 molecules of KCl and 1 molecule of F2 react?
2.
What atoms are in KCL?
K+ And CL- or Potassium and chlorine.
What are the oxidation numbers in KCl?
The oxidation numbers for the atoms in the ionic compound KCl are K+1 and Cl-1.
How many ml of 0.25M KCl are needed to provide 0.012 moles of KCl?
0.012mol KCl x (1L/0.25mol KCl) x (1000ml/1L) = 48 mL KCl
Is potassium a cation or anion?
Potassium Chloride (KCl) is neither an anion or a cation, as these have negative and positive charges respectively. K+ is the cation of KCl, and Cl- the anion. An atom is the smallest unit of an element that gives the element its properties, so therefore, KCl is not an atom either (K and Cl are made up of atoms). Consequently, you could deduce that KCl is a molecule, however, you would be incorrect as the word 'molecule' suggests that the K-Cl bond is a covalent bond, which it is not. The K-Cl bond is ionic, therefore making KCl a compound. Hope this helps! John S :-)
How many moles of KCl in 0.90M KCl?
The answer is of course 0,9 M.
