Answer:
17.83M
Explanation:
Given parameters:
Mass of KCO₂ = 1.5kg
Volume of water = 850mL
Unknown:
Molarity of solution = ?
Solution:
Molarity is defined as the number of moles per unit volume. It is the number of moles of solute in a given volume of solution.
Molarity =
Number of moles of solute =
Molar mass of KCO₂ = 39 + 12 + 3(16) = 99g/mol
Number of moles = = 15.15moles
850mL : gives 0.85L
Molarity = = 17.83M
