What is 3 m NaOH?
Explanation: A 3.0 M solution of NaOH has 3.0 moles of NaOH per liter of solution. There are 0.25 L of solution (250mL⋅1L1000mL) , so there are 0.25L⋅3.0mol/L=0.75mol of NaOH. The molar mass of NaOH is 40.0 g/mol, so there are 0.75mol⋅40.0g/mol=30g of NaOH, 30.
How do you make 3 m NaOH?
Frequently Asked Questions About Solution Preparation
- Katie Owens.
- How do I make ___ mL of a ___ molar solution?
- Determine molarity required: M = 3M solution = 3 moles NaOH/1 L of solution.
- Determine molar mass: MM of NaOH = 40 g/mol.
- Convert volume required to liters: V = 100 mL x 1 L/1000 mL = 0.1 L.
What is the molecular weight of NaOH?
39.997 g/molSodium hydroxide / Molar mass
What is 2.5 m NaOH?
Explanation: Well, know that 1 M=1 mol/L . So, a solution with a concentration of 2.5 M NaOH would mean 2.5 moles of sodium hydroxide per one liter of this solution.
What is the molecular structure of NaOH?
NaOHSodium hydroxide / Formula
How do you make a 10% NaOH solution?
Never add water to an acid. Therefore, 4 g of NaOH dissolved in one litre of solution will give N/10 NaOH solution. Weigh quickly 4 g NaOH in a beaker (as it is hygroscopic) and dissolve it in distilled water (preferably CO -free).
How do you make 5m NaOH?
Work in fume hood! Weigh out 30 g NaOH . Add to 500 mL beaker. Measure out 250 mL milliQ water and add to beaker.
What is 0.1 N NaOH?
Making 1 N solution of NaOH To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume 1 liter. For a 0.1 N solution (used for wine analysis) 4.00 g of NaOH per liter is needed.
How do you prepare 750ml of 1M NaOH?
To make 1 M NaOH solution, you have to dissolve 40.00 g of sodium hydroxide pellets in 250 mL distilled water and then make up the solution to 1 liter. Weigh 19.95 gm of NaOH pellets & dissolve them in half liter(500ml) of distilled water water, what you will be having now is 1M NaOH solution.
How would you prepare a 10% solution of NaOH?
