How many milliliters of 0.1256 M NaOH are required to provide 1.852 g of NaOH?

mols NaOH = grams/molar mass

Calculate mols NaOH needed.
Then M = mols/L
You have mols and M, calculate L.

that makes no sense....better explanation please

Then you didn't read it very carefully. I'll draw you a picture.

mols NaOH = grams/molar mass
You have grams NaOH of 1.852. You can get molar mass NaOH. Calculate mols NaOH.


Calculate mols NaOH needed.The above does that calculation for you but you must plug in the numbers and punch the calculator.

Then M = mols/L
You have mols and M, calculate L.
The definition of molarity is mols/L.
You have mols from the first calculation. You have Molarity from the problem of 0.1256. The only unknown in M = mols/L is L. You must calculate that yourself.

There is a neat equation that I've always used but the modern teachers don't use it.

L x M x molar mass = grams.

To find out how many milliliters of 0.1256 M NaOH are required to provide 1.852 g of NaOH, we can use the concept of molarity (M) and the equation:

Molarity (M) = moles of solute / volume of solution in liters

First, we need to calculate the moles of NaOH using the given mass and its molar mass.

1. Convert the given mass (1.852 g) to moles. To do this, divide the mass by the molar mass of NaOH.

The molar mass of NaOH is calculated by summing the atomic masses of Na (22.99 g/mol), O (16.00 g/mol), and H (1.01 g/mol).
Molar mass of NaOH = 22.99 g/mol + 16.00 g/mol + 1.01 g/mol = 39.00 g/mol

1.852 g / 39.00 g/mol = 0.0474 moles

Now, we have the moles of NaOH.

Next, we can use the molarity equation to find the volume of 0.1256 M NaOH required to provide 0.0474 moles of NaOH. Rearranging the equation gives us:

Volume = moles of solute / molarity of solution

Volume = 0.0474 moles / 0.1256 M = 0.377 L

Since the given molarity is in liters, we need to convert it to milliliters by multiplying the volume by 1000.

0.377 L * 1000 mL/L = 377 mL

Therefore, 377 milliliters of 0.1256 M NaOH are required to provide 1.852 g of NaOH.
