A mixture that results when substances dissolve to form a homogeneous mixture is a solution.
Answer:
[CaCl₂·2H₂O] = 1.43 m
Explanation:
Molality is mol of solute / kg of solvent.
Mass of solvent = 40 g
Let's convert g to kg → 40 g / 1000 = 0.04 kg
Let's determine the moles of solute (mass / molar mass)
8.43 g / 146.98 g/mol = 0.057 mol
Molality = 0.057 mol / 0.04 kg → 1.43
Answer: b
explanation: i had the question on a test and got it right.
You’ll need to be sure to count all the atoms in each side of the chemical equation.
If you know the Table of elements you can see it on.
