Answer: 0.537 moles
Step-by-step explanation:
Hello, Let's first explain the term molarity
---> Molarity is the most commonly used term to describe the concentration of a solution. It is equal to the moles of solute divided by the liters of solution.
---> The solute is defined as the substance being dissolved, while the solvent is the substance where the solute is dissolved (usually water).
---> The solution is the combination of the solute and the solvent.
Molarity = moles of solution/Liters of
solution
Parameters given are
Volume(V) = 179ml of CaCl2 solution
Molarity = 3.0m
Therefore,
Molarity = number of moles of CaCl2 solution / Volume of CaCl2 in Liters (eqn 1)
First, convert 179ml to liters
1ml = 0.001L
179ml = ?
179ml = 179ml x 0.001L
= 0.179L
From (eqn 1)
Let the number of moles of CaCl2 solution be M
=> 3 = M/0.179
M = 0.179 x 3
= 0.537 moles
Hence the number of moles in 179ml of CaCl2 solution yields 0.537 moles
