How many moles of sodium sulfate will be formed if you start with 2.00 moles of sodium

Chemistry
1 answer:
dimaraw [331]2 years ago
3 0

Answer:

The molecular weight of sodium sulfate is 142.1 g/mol. To calculate the mass of sodium sulfate, substitute the values in the formula. Therefore, the mass of sodium sulfate formed when we start with 200.0 grams of sodium hydroxide and you have excess sulphuric acid is 355.25g.

. An atom of nitrogen has an atomic
GrogVix [38]

Here's the Answer !

Atomic number = no. of electrons = no. of protons, therefore :

  • no. of electrons = 7

  • no. of protons = 7

and mass number = no. of protons + no. of neutrons

so,

  • 7 + no. of neutrons = 14

  • no. of neutrons = 7

In a sulphuric acid (h2so4) - sodium hydroxide (naoh) acid-base titration, 17.3 ml of 0.126 m naoh is needed to neutralize 25 ml
katen-ka-za [31]
The balanced equation for the neutralisation reaction is as follows
2NaOH + H₂SO₄ ---> Na₂SO₄ + 2H₂O
stoichiometry of NaOH to H₂SO₄ is 2:1
the number of moles of NaOH reacted  - 0.126 mol/L  x 0.0173 L = 0.00218 mol
if 2 mol of NaOH reacts with 1 mol of H₂SO₄ 
then 0.00218 mol of NaOH reacts with - 0.00218 / 2 = 0.00109 mol of H₂SO₄ 
molarity is the number of moles of solute in 1 L solution
therefore if 25 mL contains - 0.00109 mol 
then 1000 mL contains - 0.00109 mol / 25 mL  x 1000 mL = 0.0436 mol/L
therefore molarity of H₂SO₄ is 0.0436 M
