Question

the number of moles of KCL in 1000ml of 3 molar solution is

Answer 1

Given:

Molarity of solution = 3

Volume of solution = 1000mL = 1 liter

To find:

Number of moles of KCl in 1000mL of 3 molar solution

Formula to be used:

$Molarity = \frac{Number of moles of solute}{Volume of solution in L}$

Calculation:

$Molarity = \frac{Number of moles of solute}{Volume of solution in L}$

$Molarity\times Volume of solution = Number of moles of solute$

$3M\times1L = Number of moles$

3 = Number of moles

Conclusion:

Thus it can be inferred that 1000ml of 3 molar solution of KCl contains 3 moles of KCl.
