To find the number of moles in 74g of KCl, you first need to calculate the molar mass of KCl. The molar mass of KCl is the sum of the atomic masses of potassium (K) and chlorine (Cl), which is 39.10 g/mol + 35.45 g/mol = 74.55 g/mol. Then, divide the given mass by the molar mass to get the number of moles: 74g / 74.55 g/mol ≈ 0.993 moles of KCl.

How many grams of KCl to make 50 mL of 2.45 M KCl?
To calculate the grams of KCl needed, first calculate the moles of KCl required using the molarity formula. Then, convert moles to grams using the molar mass of KCl, which is approximately 74.55 g/mol.
How many Cl- ions are present in 2.00 mol of KCl?
There are 2.00 mol of KCl, which means there are 2.00 mol x 1 Cl- ion per KCl = 2.00 mol Cl- ions present in 2.00 mol of KCl.
How many grams of KCl are required to prepare 2.25L of a 0.75m KCl solution?
To calculate the grams of KCl needed, first determine the molar mass of KCl (74.55 g/mol). Then use the formula: grams = molarity x volume (L) x molar mass. Plugging in the values, you get: grams = 0.75 mol/L x 2.25 L x 74.55 g/mol = 126.60 grams of KCl.
How many grams of kCL will dissolve in 100 grams of H2O at 10 digrees Celsius?
Approximately 34 grams of KCl will dissolve in 100 grams of water at 10 degrees Celsius. This is the solubility limit of KCl at that temperature.
How many ml of 0.25M KCl are needed to provide 0.012 moles of KCl?
To find the volume of 0.25M KCl needed to provide 0.012 moles of KCl, you can use the formula: moles = Molarity x Volume (in liters). Rearranging this formula to solve for Volume gives Volume = moles / Molarity. Plugging in the values, Volume = 0.012 moles / 0.25 mol/L = 0.048 L = 48 ml.
How many tablespoons in 74g?
Depends what you measure. 74 grams of water is 6 tablespoons.
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
What will occur when 6.7 mols of Na reacts with 3.2 mols of Cl2?
you would get 6.4 mols of NaCl and 0.3 mols of unreacted Na
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 grams in 0.50 mols of H2so4?
49.03924
How many mols are in 400g MgO?
The answer is 9,92 moles.
How many moles of ions AL3 and how many mols of ions CL-has in 0.9 mols of ALCL3?
I suppose that the answers are: - 0,9 moles aluminium ions - 2,7 moles chloride ions
When was Mols-Linien created?
Mols-Linien was created in 1964.
What is the birth name of Christine Dea Mols?
Christine Dea Mols's birth name is Dea Christine Hellstrm Mols.
How many atoms are in KCL?
There are two types of atoms in KCl, potassium (K) and chlorine (Cl). The chemical formula KCl indicates that there is one atom of potassium and one atom of chlorine in each molecule of KCl.
How many moles of KCl are contained in 121mL of a 1.68M KCl solution?
Molarity is moles of solute per L of solution.moles KCl = ( 1.68 M ) ( 0.121 L ) = ( 1.68 mol/L ) ( 0.121 L )moles KCl = 0.203 moles KCl
