A mixture of KCl and KNO3 is 44.20 percent potassium by mass the percentage of kcl in the mixture is?
40%
What mass of KCl would be needed to form a saturated solution if the KCl was dissolved in 200 g of water at 80 C?
Minimum 102,6 g of KCl.
How many grams of KCl are needed to make 100 ml of a 3.5M solution?
In a 3.4 M solution, there are 3.4 moles per liter. If you want to make 3 liters of solution, you'll need 3 liter * 3.4 moles/liter = 10.2 moles The molar mass of KCl is 39.098 g/mole K + 35.453 g/mole Cl = 74.551 g/mole KCl To get the number of grams, multiply the number of moles by the molar mass: 10.2 moles * 74.551 g/mole KCl = 760.4202 g = 0.760 kg
How much kcl require for prepaire 3M kcl?
Molar mass of KCl = 74.55g/mol.ie, if you dissolve 74.55g KCl in 1litre (1000 ml) of water, it will be 1M KCl solution.If you want to make 3M KCl solution,Dissolve 3 ×74.55 = 223.65g KCl in 1litre (1000 ml) of water.If you want to make different molar solutions of KCl, just calculate as per below given equation.Weight of KCl to be weighed =Molarity of the solution needed × Molecular weight of KCl (ie, 74.55) × Volume of solution needed in ml / 1000.To prepare 3M KCl in 1 litre, it can be calculated as follows,3 mol × 74.55 g/mol × 1000 ml / 1000 ml = 223.65gByPraveen P Thalichalam, Kasaragod (Dist), Kerala.
How many milliliters of 0.1250 M KCl solution contain 2.330 g of KCl?
First find the molar mass of KCl: 39.098 + 35.453 = 74.551 g/mol2.330g KCl/74.551 g/mol = 0.03125 mol KCl0.1250 M = 0.1250 mol/Lx Liters * 0.1250 mol/L = 0.03125 molx = 0.250 L = 250 mL
What is the balanced equation for heating potassium chloride?
There is no reaction (decomposition) when KCl is heated, other than the melting of KCl, above its melting point.
A mixture of KCl and KNO3 is 44.20 percent potassium by mass the percentage of kcl in the mixture is?
40%
What mass of KCl would be needed to form a saturated solution if the KCl was dissolved in 200 g of water at 80 C?
Minimum 102,6 g of KCl.
What is the heated balanced formula for potassium chlorate?
2KClO3 + HEAT = 2 KCl + 3 O2
If the mass with 0.1 grams of MNO2 is 53.300g and 20 g of KCl O3 is 73.300g and after burning it so only KCl remains is 65.467 g what is mass of potassium chloride?
7.533
How many moles are in 48g of KCl?
KCl has a molar mass of 39+35.5=74.5g/mol, and 48/74.5=0.64mol.
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 many grams of KCl are needed to make 100 ml of a 3.5M solution?
In a 3.4 M solution, there are 3.4 moles per liter. If you want to make 3 liters of solution, you'll need 3 liter * 3.4 moles/liter = 10.2 moles The molar mass of KCl is 39.098 g/mole K + 35.453 g/mole Cl = 74.551 g/mole KCl To get the number of grams, multiply the number of moles by the molar mass: 10.2 moles * 74.551 g/mole KCl = 760.4202 g = 0.760 kg
What mass of KCL would have to be dissolved in 2L of H2O in order to make 4M solution?
This mass is 596,41 grams.
According to the law of definite proportions any two samples of KCl have?
They will have the same mass.
What is the mass of K2O contain equal number of moles of K atoms as are present in 1kg of KCl?
This mass is 631,75 g K2O.
How many grams of potassium chloride is contained in 750 ml of 1.25 M KCl solution?
we know that, molarity=(given mass/molar mass)*(1000/volume of solution in ml) all the dats are given,only we have to find out the given mass or the present mass of the KCl. 1.25=(given mass/74.5)*(1000/750) => given mass=(1.25*750*74.5)/1000 =69.84g.
