The formula is B2O3. The charges need to equal each other to obtain a neutral compound of no charge hence 2 B has a charge of +6 and 3 O has a charge of -6 to cancel out each other, resulting in a stable uncharged compound.
"pH = - log[H3O+]
13 = - log[H3O+]
-13 = log[H3O+]
Log[H3O+] = -13
Log10 [H3O+] = -13
10^-13 = [H3O+]
[H3O+] = ?"
Answer:
Number of moles = 0.94 mol
Explanation:
Given data:
Number of moles of sodium chloride = ?
Volume of sodium chloride = 1.25 L
Concentration of solution = 0.750 mol/L
Solution:
Formula:
Concentration = number of moles/ volume in L
By putting values.
0.750 mol/L = number of mole / 1.25 L
Number of moles = 0.750 mol/L×1.25 L
Number of moles = 0.94 mol
