Calculate the mass of KI in grams required to prepare 5.00 X10^2 mL of a 2.80 M solution
2 answers:
Explanation:
Molarity refers to moles per liter of solution, while the number of moles is defined as mass divided by molar mass.
Consequently, Molarity =
Given that the molarity is 2.80 M, the volume is 500 mL or 0.5 L, and the molar mass of KI is 166 g/mol.
Thus, mass =
=
= 232.4 g
Therefore, the mass of KI required to prepare 5.00 X10^2 mL of a 2.80 M solution is 232.4 g.
