What is the mass in grams of 25 mol of sodium hydroxide?
It is 25 moles of Sodium Hydroxide (;
Calculate mass of 4.00 moles of sodium?
well take sodium, which the molar mass is 23.0 g/mol and multiply by # of moles (4) and you get 92g
How many moles of sodium hydroxide will react with 17 moles of sulfuric acid?
In the acid-base reaction where sodium hydroxide and sulfuric acid react, the formula is: H2SO4 + 2NaOH --> Na2SO4 + 2H2O. The coefficients shown are necessary to uphold the law of conservation of mass. So, if you have 17 moles of sulfuric acid, you will need twice as many moles of sodium hydroxide, so the answer is 34 moles NaOH.
How many moles are in 4.75g of sodium hydroxide?
The gram molecular formula unit mass of sodium hydroxide is 40.00. Therefore,4.75 g constitutes 4.75/40.00 or 1.19 X 10-1 mole, to the justified number of significant digits.
Which is the mass of 8 moles of sodium chloride?
Sodium chloride has a molar mass of about 58.5 g/mol. So multiply 8 moles by molar mass to get about 468 grams.
What is the mass in grams of 25 mol of sodium hydroxide?
It is 25 moles of Sodium Hydroxide (;
How many millimoles are in 12g of sodium hydroxide?
The molecular weight of sodium hydroxide is 40g/mol. To get the amount of moles, you have to divide the weight by molecular mass. 12g / 40 is 0.3 moles. This is 300 millimoles.
Calculate mass of 4.00 moles of sodium?
well take sodium, which the molar mass is 23.0 g/mol and multiply by # of moles (4) and you get 92g

So, if you have 17 moles of sulfuric acid, you will need twice as many moles of sodium hydroxide, so the answer is 34 moles NaOH.
How many moles are in 272g?
It depends on what the subtance is, i.e. whether there is 272g of copper, sodium chloride, lithium hydroxide or what. The way to calculate the amount of a subtance in moles is to divide the mass of the substance (in grams) by the atomic mass, molecular mass or formula mass of the element, molecular compound or ionic compound respectively, as the case may be.
How many atoms of sodium are present in Moles of sodium and what is the mass of it?
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
How many atoms of sodium are present in 3 moles of sodium and what is the mass of it?
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
How many grams does 2.2 moles of NaOH weigh?
Need total molar mass sodium hydroxide which you can easily get from your periodic table. 2.2 moles NaOH (39.998 grams/1 mole NaOH) = 88 grams in mass ==============
How many moles of sodium hydroxide are formed when 46 g of sodium react with water?
First construct a a balanced equation for the reaction : 2Na + 2H2O --> 2NaOH + H2 From the equation, we know that the ratio of Sodium(Na) to the ratio of Sodium Hydroxide(NaOH) is the same. Ar of Na = 23g/mol Number of moles = mass / Ar = 46g / 23g/mol = 2mol (moles of Na used) Since ratio of Na to NaOH is the same, therefore there are also 2 moles of NaOH formed.
How many moles are in 4.75g of sodium hydroxide?
The gram molecular formula unit mass of sodium hydroxide is 40.00. Therefore,4.75 g constitutes 4.75/40.00 or 1.19 X 10-1 mole, to the justified number of significant digits.
How many atoms of sodium are present in 3 mole of sodium and what is the mass of it?
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
What is the molar mass of sodium and hydroxide?
Sodium has a molar mass of 23 Hydroxide (Hydrogen & Oxygen) have a molar mass of 17 23+17=40g/mol 40grams per mole
