I assume you mean 32.0 grams of NaOH and 450 milliliters of NaOH.

Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters )

get moles of NaOH

32.0 grams NaOH (1 mole NaOH/39.998 grams)

= 0.800 moles NaOH

Molarity = 0.800 moles NaOH/0.450 liters

= 1.78 Molar NaOH

What volume of a 6.0Mol solution do you need to make a 450ml solution with a molarity of 2.5M?

187.5 ml of the 6.0 Molar solution mixed with (I assume) 262.5 ml water will produce 450ml of 2.5M.This can be solved with a system of equations. Assign variables x and y to be the quantities of the two respective liquids, say x for the 6.0M solution and y for the water.We know one equation is x + y = 450ml.Also, if I make an equation of Molarity x qty, I get:6.0x + 0y = 450*2.5which is 6x = 1125So my system of equations is:6x = 1125x + y = 450From here you should be able to easily solve for x from the first equation, then substitute for x into the second equation to find y.You should really get this whole mixing thing down before you embark upon consumption of alcoholic beverages. Just a little advice. :) 1 shot Everclear does not equal 1 shot JD. Why? Different %alcohol by volume! Sorry about that tangent...
