The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles KCl, or 74.5513 grams.
How much does a mole of KCl weigh?
Since 1 mole of KCl contains 1 mole of K (39.1g) and 1 mole of Cl (35.5g), the molar mass of KCl is 74 . 6 g/mol.
How many grams of KCl are produced?
Find the gram molecular mass of Potassium Chloride. = 74.4 grams / mole. Ernest Z. The reaction will produce 15.3 g of KCl .
How many grams of KCl are produced if 25g of kclo3 decompose?
Therefore 15.2 g of KCl would be formed.
What is the equivalent weight of KCl?
Therefore, the answer is – option (B) – The equivalent weight of KCl is 74.5. Additional Information: Equivalent weight is unit less, because it is a relative quantity.
What is the formula weight of KCl?
Answer and Explanation: The molar mass of a compound is calculated by multiplying the sum of the relative atomic mass Ar of the constituent atoms by the molar mass constant Mu . Where, Mr is the relative molar mass. Hence the molar mass of KCl is obtained as 74.5513 g mol−1 74.5513 g m o l − 1 .
How do you find the equivalent weight of KCl?
of its gram equivalent weight taking into account the valence of the ions. KCl? Step 3: 1 mEq KCl = 1/1000 x 74.5 g = 0.0745 g = 74.5 mg Step 4: 1 mEq KCl = 74.5 mg; 1.5 g KCl = 1500 mg; How many mEq in 1500 mg?
How many moles are in KCl?
One mol of KCl is equal to 74.6 grams (from the periodic chart, the gram-atomic mass of potassium is 39.0 and that of chlorine is 35.5. Add together for the gram-molecular mass of 74.6). If you took 74.6 grams of KCl and diluted this to one liter with water, you would have a 1.00 M KCl solution.
How many grams is 0.5 moles of KCl?
The chemist uses the number of moles to get the mass or volume of a gas at 22.4 liters per mole at STP. So 0.5 mole of KCl is 0.5 x 6.02 x 10^23 = 3.01 x 10^23 KCl has a molar mass of (K = 39.1 g/mol + Cl = 35.5 g/mol ) is 74.6 g/mol. So weighing 37.3 g gives you 0.5 mole).
How many moles are in 74 g of KCl?
74g KCl = 0.99 mole of KCl (molar mass KCl= 74.6g)
How do I calculate moles?
How to find moles?
- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.
How do you convert from grams to moles?
Divide the number of grams of the compound, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).
