what is the concentration (molarity) of a solution where 149g of kcl is dissolved in enough water to get a total volume of the s

Anit [1.1K]

Molar mass KCl = 74.55 g/mol

Number of moles:

mass KC / molar mass

149 / 74.55 => 1.998 moles

Volume in liters: 500 mL / 1000 => 0.5 L

Therefore:

M = moles / volume

M = 1.998 / 0.5

M = 3.996 mol/L⁻¹
