Based on the concentrations given, the volume of vinegar required is 5.04 mL.
<h3>What is the concentration of the vinegar solution?</h3>
The concentration of a solution is the amount of solute in a given volume of solution.
Concentration can be expressed as:
- molar concentration
- percentage concentration
The concentration of the vinegar solution is 4.76% (w/w). This means that 4.76 g of vinegar is present in 100 g of solution.
Mass of vinegar = 4.76 g
molar mass if vinegar = 60 g/mol
moles of vinegar = 4.76/60 = 0.0793 moles
volume of solution/water = 100 mL or 0.1 L
Molarity of vinegar = 0.0793/0.1 = 0.793 M
1 mole of vinegar reacts with 1 mole of NaOH
let the volume of vinegar required be V
0.793 M × V = 40 × 0.1
V = 4/0.793
V = 5.04 mL
Therefore, the volume of vinegar require is 5.04 mL.

Answer:
Mass = 185.896 g
Explanation:
Given data:
Mass in gram = ?
Number of moles = 2.00 mol
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of cobalt (I) hydroxide =92.948 g/mol
by putting the values,
2.00 mol = Mass/92.948 g/mol
Mass = 2.00 mol × 92.948 g/mol
Mass = 185.896 g

Answer : The final concentration of copper(II) ion is, 0.198 M
Explanation :
First we have to calculate the moles of and .
Moles of = Moles of = 0.00459 mol
and,
Moles of = Moles of = 0.00869 mol
Now we have to calculate the total moles of copper(II) ion and total volume of solution.
Total moles copper(II) ion = 0.00459 mol + 0.00869 mol
Total moles copper(II) ion = 0.0133 mol
and,
Total volume of solution = 40.6 mL + 26.4 mL = 64.0 mL = 0.067 L (1 L = 1000 mL)
Now we have to calculate the final concentration of copper(II) ion.
Thus, the final concentration of copper(II) ion is, 0.198 M
Answer:
Lithium Bromide: LiBr and Potassium chloride: KCl.
Explanation:
A substance that will conduct electricity when dissolved completely in water is known as an Electrolyte.
Now, electrolytes are usually salts that ionize completely in a solution unlike non - electrolytes that do not dissociate into ions in solution.
Looking at the options, the only ones that are Salts are Lithium Bromide: LiBr and Potassium chloride: KCl.
Thus, options
