Final answer:
To calculate the mass of KCl in the solution, use the formula Mass = Molarity x Volume x Molar Mass. The mass of KCl in 50.0 mL of a 3.12 M KCl solution is 11.09 g.
Step-by-step explanation:
To determine the mass of KCl in the solution, we can use the formula:
Mass = M (Molarity) x V (Volume) x Molar Mass
Now, convert the given volume in mL of the solution to (L):
50.0 mL = 0.050 L
Next, plug the values into the formula:
Mass = 3.12 M x 0.050 L x (molar mass of KCl)
The molar mass of KCl is 74.55 g/mol. Calculate the mass of KCl:
Mass = 3.12 M x 0.050 L x 74.55 g/mol = 11.09 g
