2.00L of a 1.50M NaOH solution 2. How many grams of pure, solid NaOH are required to make 400 mL of 0.1M NaOH solution? mass NaOH=40*0.4= 16 g. Weight 16 g of NaOH and fill with water till the 200 mL mark you are making 2 L here so you must have 1.5*2=3 moles. 25.0 mL of a 6.00 M HCl solution
?

Calculate the mass: mass=mol*MW. So the equivalent weight of NaOH is 40.

See below. "to prepare a 0.2N NaOH solution we will have to mix 0.2 moles of NaOH to one litre of water. The molecular weight of 1 mole is 39.997 g Since 1 M in 1L NaOH solution contains 39.997 g ∴ 0.2 M in 1L solution contains 39.997 *0.2 =... See full answer below. I hope the conversion is just a tenth. G.M.M. To prepare Carbonate Free NaOH, please see, Vogel's Textbook of Quantitative Chemical Analysis, 5th.Ed.1989, page 289; Thank You and Good Luck Cite 1 Recommendation you require 3 moles so 40*3=120 gms 4.00L of a 0.200M KCl solution 3. i make 0.2 M NaOH and i weight out 27.22grams of NaOH pellets in liter of water. NaOH is often used to teach about pH in high schools and it can neutralize HCl. How to prepare a {eq}\rm 500\ ml\ 0.2\ M\ NaOH {/eq} solution from {eq}\rm 2.0\ M\ NaOH {/eq} solution? To make 500 mL of 2.00 M NaOH solution, you need to make sure that every litre of the solution contains 2.00 mol of NaOH. Calculate the mol by the equation: Concentration(M)=mol/Volume(L) mol=C*V=2*0.200= 0.4 mol. Express your answer to 2 significant figures. Using some simple supplies, you can make homemade NaOH for use in the lab, or just to impress your colleagues and students. of NaOH is 40 gms i.e. 1 mole of NaOH has mass of 40 gms . 1.5 M solution means that you have 1.5 moles of NaOH per Litre . Sodium hydroxide, lye, and caustic soda all refer to the same compound, NaOH, which is comprised of 3 single atoms: sodium, oxygen, and hydrogen. 1. So, 1 L of 2.00 M NaOH solution contains 2.00 xx ("23.0 + 16.0 + 1.0) g NaOH". And 500 mL of 2M NaOH solution contains 80.0/2color(white)(l) "g NaOH" = "40.0 g of NaOH". in one liter measure out 272 grams of NaOH pellets. To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume 1 liter. 1) Weigh out 400 grams (10 moles) of NaOH pellets. Make sure to use goggles and gloves, because sodium hydroxide is very caustic, and the mixture can get very hot (reaction is very exothermic). From the discussion above, it should be clear that to make 1 Normal solution we need to know the, equivalent of NaOH, which is calculated by dividing Molecular weight by 1, that is 40 divided by 1= 40.
