Answer:

To find the molarity of the solution, we first need to calculate the number of moles of ethanol (C2H5OH) in 4.6 grams and then divide by the total volume of the solution in liters.

Given:

Mass of ethanol (C2H5OH) = 4.6 g

Molar mass of ethanol (C2H5OH) = 46 g/mol

Volume of solution = 200 ml = 0.2 L

First, calculate the number of moles of ethanol:

Number of moles = Mass / Molar mass

Number of moles = 4.6 g / 46 g/mol = 0.1 mol

Now, calculate the molarity of the solution:

Molarity (M) = Number of moles / Volume of solution (in liters)

Molarity = 0.1 mol / 0.2 L = 0.5 M

So, the molarity of the solution is 0.5 M.

Answer:

To find the molarity of the solution, we need to calculate the number of moles of C2H5OH and then divide it by the volume of the solution in liters.

First, let's calculate the number of moles of C2H5OH:

Number of moles = mass / molar mass

Number of moles = 6 g / 46 g/mol

Number of moles ≈ 0.1304 mol

Next, let's convert the volume of the solution from milliliters to liters:

Volume = 200 ml = 200/1000 = 0.2 L

Now we can calculate the molarity of the solution:

Molarity = Number of moles / Volume

Molarity = 0.1304 mol / 0.2 L

Molarity ≈ 0.652 M

Therefore, the molarity of the solution is approximately 0.652 M.
