Answer:
1.86 m
Explanation:
Step 1: Calculate the mass of solute and solvent in 100 grams of solution
We have a 15.0% by mass solution of MgCl₂ (solute) in H₂O (water). In 100 g of solution, there are 15.0 g of solute and 100.0 g - 15.0 g = 85.0 g of solvent.
Step 2: Calculate the moles corresponding to 15.0 g of MgCl₂
The molar mass of MgCl₂ is 95.21 g/mol.
Step 3: Convert the mass of water to kilograms
We will use the relationship 1 kg = 1,000 g.
Step 4: Calculate the molality of the solution
Answer: Lithium—7 is more abundant with 94.1%
