How many ions of Na plus are released by 1 mole of NaOH?
Since NaOH is a strong base, one mole (6.022x1023) of Na+ ions are formed when one mole of NaOH dissolves in water.
How many NaOH required to neutralize complitly4.9 gms of H2SO4?
Grams NaOH?? Balanced equation. 2NaOH + H2SO4 --> Na2SO4 + 2H2O 4.9 grams H2SO4 (1 mole H2SO4/98.086 grams)(2 mole NaOH/1 mole H2SO4)(39.998 grams/1 mole NaOH) = 4.0 grams NaOH needed =================
How many moles of NaOH are in 8 g of NaOH?
8 grams NaOH (1 mole NaOH/39.998 grams) = 0.2 moles NaOH
How many moles of sodium hydroxide are in 15 grams of the compound?
1 mole NaOH = 39.99664g (from the atomic weights on the periodic table) 15g NaOH x 1mol/39.99664g = 0.38 mole NaOH
How many hydrogenn atoms are in NaOH?
There is one hydrogen atom in one formula unit of NaOH.
How many molecules are in NaOH?
This is acetic acid which is monobasic acid so one mole of it is neutralized by one mole of NaOH.
How many ions of Na plus are released by 1 mole of NaOH?
Since NaOH is a strong base, one mole (6.022x1023) of Na+ ions are formed when one mole of NaOH dissolves in water.
How many moles of NaOH are in 8 g of NaOH?
8 grams NaOH (1 mole NaOH/39.998 grams) = 0.2 moles NaOH

1 mole NaOH = 39.99664g (from the atomic weights on the periodic table) 15g NaOH x 1mol/39.99664g = 0.38 mole NaOH
What is the mass of 3.42 moles of NaOH?
3.42 moles NaOH (39.998 grams/1 mole NaOH) = 137 grams NaOH
How many moles are there in 8 g sodium hydroxide?
8 g NaOH x 1 mole NaOH/40 g = 0.2 moles NaOH
How many hydrogenn atoms are in NaOH?
There is one hydrogen atom in one formula unit of NaOH.
Are 0.5 mole of NaOH and 0.5M of NaOH solution same?
No, they are not. "0.5 mole of NaOH" means that you have half a mole of sodium hydroxide. "0.5M of NaOH" means that you have half a mole of sodium hydroxide for every liter of solution. "0.5M" is also commonly written as "0.5 mol/L" or "mol L-1".
If you have 60 grams of sodium hydroxide NaOH (FW 40 gramsmole) how many moles of sodium hydroxide would you have?
60 g NaOH x 1 mole NaOH/40 g NaOH = 1.5 moles NaOH
How many grams of sodium sulfate will be formed if you start with 12.5 grams of sodium hydroxide and you have an excess of sulfuric acid?
Balanced equation. 2NaOH + H2SO4 -> Na2SO4 + 2H2O 12.5 grams NaOH (1 mole NaOH/39.998 grams)(1 mole Na2SO4/2 mole NaOH)(142.05 grams/1 mole Na2SO4) = 22.2 grams sodium sulfate produced ===========================
How many atoms are in 10 grams of sodium hydroxide?
sodium hydroxide is NaOH so its atomic mass is 23+1+16=40 so one mole of NaOH contains 40 grams and 6.023*10^23 molecules hence 10 grams will have 0.25 moles and hence 0.25*6.023*10^23 molecules ==1.0575 *10^23 molcules now 1 molecule of NaOH has 3 atoms so total no of atoms in 10 gram is 1.0575*3*10^23=1.592330625810^23 atoms
