Answer:
<em>Well, Your best answer will be is 2H+ + 2OH- -> 2H2O but you have to reduce it to H+ + OH- -> H2O. </em><em>Good Luck!</em>
The answer is natural gasses
Explanation:
Molar mass of O2: 32g/mol
Moles of O2 = 19.5 / 32 = 0.609mol
1 mole of NaCl has (23+35.5)g= 58.5g
Therefore, to make 1M/L of solution you will need 58.5g Then to make 0.5M/L you will need 58.5/2=29.25g
If to make 1liter of 0.5M one will need 29.25 grams of NaCl, then250g of NaCl will make
(250g×1L)/29.25g= 8.547liters
