Na2O + H2O = 2NaOH
Sodium Oxide (Na2O) is a white crystalline solid.
Note the molar ratios are 1:1::2 or 1/2: 1/2 ::1
Hence
Its Mr is
2 x Na = 2 x 23 = 46
1 x O = 1 x 16 = 16
46 + 16 = 62
Using the equation
Moles = mass(g) / Mr
Then mass (g) = moles X

What is the molar mass of sodium and hydroxide?
The molar mass of sodium (Na) is 22.99 g/mol, and the molar mass of hydroxide (OH) is 17.01 g/mol. To find the molar mass of sodium hydroxide (NaOH), you can add the molar masses of sodium and hydroxide together, which equals 39.00 g/mol.
What is the density of 1 molar sodium hydroxide in grams per milliliter?
The density of a 1 M solution of sodium hydroxide is approximately 1.04 g/mL at room temperature.
What volume in mLs of 0.100 M sodium hydroxide solution must be added to 20.0 mL of 0.08 M sulfuric acid solution to reach the end point?
To neutralize the sulfuric acid completely, you need a 1:2 molar ratio of sodium hydroxide to sulfuric acid. Therefore, you would need to add twice the amount of sodium hydroxide compared to the amount of sulfuric acid, which is 40.0 mL of the sodium hydroxide solution.
An aqueous solution of sodium hydroxide contained in a bottle is labelled 2M. Determine the mass of sodium hydroxide used in preparing?
You cannot answer this without also knowing the VOLUME of the 2 M solution. For example, if you have 1 liter of 2 M NaOH, the the mass contained in that bottle will be 1L x 2 mol/L x 40 g/mol = 80 g.If, however, you have 2 liter, then the mass of NaOH contained in that bottle will be 160 g. And so on.
How do you prepare 0.2M of anhydrous of sodium thiosulphate?
To prepare 0.2M solution of anhydrous sodium thiosulfate (Na2S2O3), you dissolve 24.6g of anhydrous Na2S2O3 in distilled water and dilute it to 1 liter. This is the molar mass method, where molar mass of Na2S2O3 is 158.10 g/mol.
What is the density of 3 molar sodium hydroxide in grams per milliliter?
the molar mass of sodium hydroxide is 40g/mol mike

What is the mass of sodium hudroxide needed to prepare 100 mL of a 0.10 M solution?
The molar mass of sodium hydroxide (NaOH) is approximately 40 g/mol. To prepare a 0.10 M solution in 100 mL, you would need 1.0 g of NaOH. This can be calculated using the formula: mass (g) = molarity (M) x volume (L) x molar mass (g/mol).
What is the density of 1 molar sodium hydroxide in grams per milliliter?
The density of a 1 M solution of sodium hydroxide is approximately 1.04 g/mL at room temperature.
Given a 5 Molar sodium hydroxide Calculate how much 5 Molar base you need to make a 100 mL of a 1 M solution?
20 ml

What is the pH number of sodium hydroxide?
Sodium hydroxide does not have a pH number. The pH of a solution of sodium hydroxide depends entirely on the concentration of it in that solution. To learn how to determine the pH of a sodium hydroxide solution, see the Related Questions links.

How many grams of solid sodium hydroxide are required to prepare 400 milliliters of a 4 hundredth molar solution?
So you want 0.04M but you have 400ml, not a litre. 0.04/1000*400 is 0.016 moles wanted. 0.016*40 (molecular weight) is 0.64g
How many grams of sodium hydroxide are present in 675 mL of a 0.500M solution?
To calculate the grams of sodium hydroxide present in the solution, first calculate the number of moles using the formula: moles = Molarity (M) x Volume (L). Then, use the molar mass of sodium hydroxide (NaOH) to convert moles to grams. The molar mass of NaOH is 40 g/mol. Thus, in this case, you have 0.3375 moles of NaOH and if you convert this to grams, it would be 13.5 grams.
