How many moles of K are in KCL?

How many moles are in KCl?

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles KCl, or 74.5513 grams.

How do you find moles of KCl?

Multiply the number of atoms for each chemical multiplied by the atomic mass. Add up the results from multiplying the numbers to obtain the molar mass for the compound. For example for KCl, (1 atom X 39.0983 Potassium) + (1 atom X 35.453 Chlorine) = (74.5513 g/mol) which is the molar mass for KCl.

How many moles of KCl are produced from 25 g of K?

25122.4 = moles.

How do you make 3 molar KCl?

To make 125 mL of 3M KCl

  1. Using digital scale, place 27.96 g KCl powder into weigh boat.
  2. In 150 mL flask, mix 27.96 g KCl with 100 mL H2O.
  3. Put flask on hotplate/stirrer with stirbar until dissolved.
  4. Add H2O to bring volume to 125 mL.

How many moles of KCl are there in 35.5 g?

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 from 25g of K?

Therefore 15.2 g of KCl would be formed.

How many moles of H2 are needed to produce 2 moles CH3OH?

Explanation: The balanced equation is: 2H2+CO→CH3OH . One C, one O and 4 H on each side. From the balanced equation we know that it takes 2 moles of H2 to produce each mole of methanol, so we need 2.82 mol of H2 .

How many moles of fe2s3 are produced when 2 moles of Fe react with 3 moles?

Because the equation is balanced, we know the proportions of iron and sulfur in the reaction. For this reaction, we see that 2 moles of iron reacts with 3 moles of sulfur to form 1 mole of iron(III) sulfide.
