How many moles are in 74g of KCl?

How many moles are in 74g of KCl?

0.99 mole
74g KCl = 0.99 mole of KCl (molar mass KCl= 74.6g)

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.

What is the equivalent weight of KCl?

74.5
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.

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.

What is the formula unit mass of KCl?

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.

What is the normality of KCL?
