Answer:
The empirical formula is C2H6O
Explanation:
Please see attachment for explanation on how to solve for the empirical formula.
Water among the coast can be several degrees colder in different areas because the water is replenished and being pushed off the coast so these cooler and nutrient-rich waters rise from a depth of 50-300 meters to the surface of the ocean
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
