What is the mass of ethylene gycol dissolved in 5.00 kg of a 40.0% solution?

Answer:

3kg

Explanation:

HI friend!

Step 1 -
The Antifreeze solution lowers the freezing point of a water-based liquid.

It is composed of ethyl alcohol(solute) and water(solvent)

Step 2 -
Second, 40% Antifreeze solution means---

40% solute is present in 100 kg of Antifreeze solution.

And here, the solute is ethyl alcohol - 40kg

Step 3-
So, wate(solvent) would become= 100-40 = 60 kg

Therefore we can say that- in 100 kg of Antifreeze solution there is 60 kg water.

Step 4 - (Calculation)
Antifreeze Solution H2O

100 60

5 60/100 * 5 = 3 kg

(The above numerical means that-

If there is 100 kg of the solution, there is 60 kg of water

So, 5kg of the solution, there is 60/100 * 5 = 3kg water)

Well, well, well, it seems we have a chemistry question here! Let me put on my lab coat and goggles. Now, when you say ethylene glycol, I can't help but think about winter and antifreeze. But let's get back to the question.

To find the mass of ethylene glycol dissolved in a solution, we need to do a little math. We know that the solution is 40.0% ethylene glycol, which means that 40.0% of the total mass of the solution is ethylene glycol.

So, let's calculate! To find the mass, we can multiply the mass of the solution (5.00 kg) by the percentage of ethylene glycol (40.0% or 0.40).

5.00 kg * 0.40 = 2.00 kg

So, the mass of ethylene glycol dissolved in 5.00 kg of the 40.0% solution is 2.00 kg. Voila!

To find the mass of ethylene glycol dissolved in 5.00 kg of a 40.0% solution, we need to follow these steps:

Step 1: Determine the mass of the solution by multiplying the given volume by its density.
Step 2: Calculate the mass of solute (ethylene glycol) in the solution using the given percentage.
Step 3: Convert the mass of solute to kilograms if necessary.

Let's calculate the mass of ethylene glycol dissolved in a 40.0% solution:

Step 1: Calculate the mass of the solution:
Mass of solution = Volume of solution × Density of solution

Since the volume is not given, we can assume it to be 5.00 kg since the given information states that "5.00 kg of a 40.0% solution." Thus:
Mass of solution = 5.00 kg

Step 2: Calculate the mass of solute (ethylene glycol):
Mass of solute = Mass of solution × Percentage of solute

Mass of solute = (5.00 kg) × (40.0/100)
Mass of solute = 2.00 kg

Step 3: The mass of solute is already in kilograms since we multiplied it by a percentage. Therefore, we don't need to convert it.

So, the mass of ethylene glycol dissolved in 5.00 kg of a 40.0% solution is 2.00 kg.

To find the mass of ethylene glycol dissolved in the solution, we need to use the formula:

Mass of solute = Mass of solution x Percent concentration

Given that we have 5.00 kg of solution and a 40.0% concentration, we can calculate the mass of ethylene glycol as follows:

Mass of ethylene glycol = 5.00 kg x 40.0% = 5.00 kg x 0.40

To simplify this calculation, we multiply the mass of the solution by the decimal form of the percentage concentration (40.0% = 0.40).

Therefore, the mass of ethylene glycol dissolved in 5.00 kg of a 40.0% solution is:

Mass of ethylene glycol = 5.00 kg x 0.40 = 2.00 kg

40% (by mass) means 40g solute/100 g solution.

40 x (6000/100) = ?
