How many grams are in a mole of KCl?

Contents

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?

1. Measure the weight of your substance.
2. Use a periodic table to find its atomic or molecular mass.
3. Divide the weight by the atomic or molecular mass.
4. 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).
