Answer : The number of moles of is 0.6156 moles.
Solution : Given,
Mass of = 186.7 g
Molar mass of = 303.256 g/mole
Formula used :
Now we have to calculate the moles of .
Therefore, the number of moles of is 0.6156 moles.
Answer:
0.0634 M HCl
Explanation:
Since HCl and NaOH react in a one-to-one mole ratio, we can just use M1V1 = M2V2 to solve for M1 (the concentration of HCl)
M1 = ? M HCl
V1 = 24.30 mL HCl
M2 = 0.120 M NaOH
V2 = 12.84 mL NaOH
M1(24.30 mL HCl) = (0.120 M NaOH)(12.84 mL NaOH)
M1 = 0.0634 M HCl
A chemical bond that involves the transfer of electrons from a metal to a nonmetal and thus forms ions and the atoms in the molecule are attracted towards each other through electrostatic force of attraction are said be ionic bond. In short, the bond formed between the two oppositely charged ions.
In salt, the compound formed between sodium and chlorine is sodium chloride having molecular formula where sodium is a metal and chlorine is the non-metal. The formation of the compound takes place by transfer of an electron from sodium thus forming a cation of formula to chlorine which gains electron and thus results in an anion formation having formula . The force of attraction between these oppositely charged ions that helds them together and results in formation of compound is electrostatic force of attraction.
Hence in salt, the nature of bond between sodium and chlorine is ionic.
It increases the degree of accuracy for your results.
