If 44.7 g of KCI (MM = 74.55 g/mol) are added to a 500.0 mL volumetric flask, and water is added to fill the flask, what is the
navik [9.2K]

1.199 M is the concentration of KCI in the resulting solution.

<h3 /><h3>What are moles?</h3>

A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

No.of moles of KCI

Moles = \frac{mass}{molar \;mass}

Moles = \frac{44.7 g}{74.5513 g/mol}

= 0.599 moles

Vol.of the solution,V= 500 ml

= 0.5 liter

Molarity

Molality = \frac{Moles \;solute}{Volume \;of \;solution \;in \;litre}

Molality = \frac{0.599 moles}{0.5 liter}

= 1.199 M

Hence, 1.199 M is the concentration of KCI in the resulting solution.
