    what is the molarity of a solution that contains 0.202 mol kcl in 7.98 l solution?

    James

    Guys, does anyone know the answer?

    get what is the molarity of a solution that contains 0.202 mol kcl in 7.98 l solution? from EN Bilgi.

    What is the molarity of a solution that contains 0.202 mol KCl in 7.98 L solution?

    "0.0253 M" Molarity is a measure of a solution's concentration in terms of how many moles of solute it contains per liter of solution. So, in essence, if you have the number of moles of solute, like you do here, and the total volume of the solution expressed in liters, you can find how many moles of solute you get per liter, i.e. the molarity of the solution. Keeping in mind the fact that the moles of solute are distributed evenly in any given volume of the solution, you can say that because "7.98 L" of solution contain 0.202 moles of solute, which in your case is potassium chloride, "KCl", "1 L" of this solution will contain 1 color(red)(cancel(color(black)("L"))) * "0.202 moles KCl"/(7.98color(red)(cancel(color(black)("L")))) = "0.0253 moles KCl" So, if your solution contains 0.0253 moles of potassium chloride per liter, it follows that its molarity is equal to c = color(green)("0.0253 M") Here "M" is equivalent to "mol/L", or molar.

    Explanation:

    Molarity is a measure of a solution's concentration in terms of how many moles of solute it contains per liter of solution.

    So, in essence, if you have the number of moles of solute, like you do here, and the total volume of the solution expressed in liters, you can find how many moles of solute you get per liter, i.e. the molarity of the solution.

    Keeping in mind the fact that the moles of solute are distributed evenly in any given volume of the solution, you can say that because

    7.98 L of solution contain 0.202

    moles of solute, which in your case is potassium chloride,

    KCl , 1 L

    of this solution will contain

    1 L ⋅ 0.202 moles KCl 7.98 L = 0.0253 moles KCl

    So, if your solution contains

    0.0253

    moles of potassium chloride per liter, it follows that its molarity is equal to

    c = 0.0253 M Here M is equivalent to mol/L , or molar. Answer link

    What is the molarity of a solution that contains 0.202 moles of KCl in 7.98 L of solution?

    Unit of Molarity:

    Molarity is calculated based on two parameters: (1) the number of moles of the solute and (2) the volume of solution in liter scale. Hence, the unit of molarity is expressed as mol/L or M.
