Answer:
The answer is in the explanation.
Explanation:
A titration of H₂X with KOH produce:
H₂X + 2KOH → 2H₂O + K₂X
It is possible to obtain the moles of H₂X because the moles of KOH are the spent volume of the titration in liters × 0,455M. As for a complete titration of H₂X moles you need twice moles of KOH you know the moles of KOH obtained are half H₂X moles.
As you know the mass of the solid acid that you titrate and molar mass of acid is:
mass of acid / moles of acid. You can determine the molar mass of the unknown acid.
I hope it helps!
Because helium is lighter then the oxygen .and due to this helium gass carrier go upward easily .
Answer:
It traveled a different distance because one has 1 spring the other has 2 spring and the last has3 spring
Answer:
18 * 10^19 atoms
Explanation:
We must first convert 57.8 mg to grams.
If 1000 mg = 1g
57.8 mg = 57.8/1000 = 57.8 * 10^-3 g
Now;
If 1 gold atom has a mass of 3.27X10^-22 grams
x gold atoms have a mass of 57.8 * 10^-3 g
x = 57.8 * 10^-3 g/3.27X10^-22 g
x = 18 * 10^19 atoms
