What is the concentration of KCl if 10 g are dissolved in enough water to make 12 L?
1 answer:
Answer:
Concentration = 0.011 M
Explanation:
Molarity is given by dividing number of moles by volume in Liters
Molarity = moles/volume
But;
Number of moles = mass/molar mass
= 10 g/ 74.55 g/mole
= 0.134 moles
Therefore;
Molarity = 0.134 moles/12 L
= 0.011 M
