mols NaOH = grams/molar mass
Calculate mols NaOH needed.
Then M = mols/L
You have mols and M, calculate L.
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.
u sound like a doche bag
