Answer: 0.0164 molar concentration of hydrochloric acid in the resulting solution.
Explanation:
1) Molarity of 0.250 L HCl solution : 0.0328 M
Moles of HCl in 0.250 L solution = 0.0082 moles
2) Molarity of 0.100 L NaOH solution : 0.0245 M
Moles of NaOH in 0.100 L solution = 0.00245 moles
3) Concentration of hydrochloric acid in the resulting solution.
0.00245 moles of NaOH will neutralize 0.00245 moles of HCl out of 0.0082 moles of HCl.
Now the new volume of the solution = 0.100 L +0.250 L = 0.350 L
Moles of HCl left un-neutralized = 0.0082 moles - 0.00245 moles = 0.00575 moles
Molarity of HCl left un-neutralized :
0.0164 molar concentration of hydrochloric acid in the resulting solution.

HCl Acid + Sodium Hydroxide ----> Sodium Chloride + water.
<u>Explanation</u>:
- The reaction between an acid and a base is known as a neutralization reaction. The reaction of an acid with a base to give salt, water and heat is called neutralization.
- When hydrochloric acid reacts with sodium hydroxide, sodium chloride and water are produced.
HCl + NaOH → NaCl + H2O + Heat
- The heat evolved in the neutralization reaction raises the temperature of the reaction mixture.
- An electro-electrodialysis process (EED) is utilized to create HCl and NaOH from exchange NaCl. NaOH and HCl arrangements with purity higher than 99.9% are acquired. The experimental estimations of the transitions for HCl and NaOH are contrasted and values determined from the incorporation of the Nernst–Planck electro dispersion conditions.
Hey there !
Molar mass carbon dioxide:
CO2 = 44.01 g/mol
1) number of moles :
1 mole CO2 ------------- 44.01 g
(moles CO2) ------------ 243.6 g
moles CO2 = 243.6 * 1 / 44.01
moles CO2 = 243.6 / 44.01
=> 5.535 moles of CO2
Therefore:
1 mole -------------------- 6.02x10²³ molecules
5.535 moles ------------ ( molecules CO2)
molecules CO2 = 5.535 * ( 6.02x10²³) / 1
=> 3.33x10²⁴ molecules of CO2
There are 6.022*10^23 molecules in 1 mole of carbon
So how many will moles will be 7.87*20^7?
Let the required number of moles be ‘x’.
1 mole ———6.022*10^23
x moles———7.87*10^7
(Cross multiplication)
x=7.87*10^7/6.022*10^23
Therefore x=1.3*10^-16
