Answer:
36.0 mL
Explanation:
First, write the balanced reaction.
2HCl + Ba(OH)₂ → BaCl₂ + 2H₂O
Calculate the moles of Ba(OH)₂:
0.500 mol/L × 0.0450 L = 0.0225 mol Ba(OH)₂
Use stoichiometry to find moles of HCl:
0.0225 mol Ba(OH)₂ × (2 mol HCl / mol Ba(OH)₂) = 0.0450 mol HCl
Now calculate the volume needed at the given concentration.
0.0450 mol HCl × (1 L / 1.25 mol) = 0.0360 L HCl
You need 36.0 mL of 1.25 M HCl.

Density, Mass and Volume</h3>
Given Data
- Density of Sulfuric acid = 1.84 g/cm3
- Mass of Sulfuric acid = 184.33 Pounds
Conversion from pounds to Gram
1 kg ---------2.204 lb
x kg ---------184.33 lb
x = 184.33/2.204
x = 83.634 kg
hence the mass in gram = 83.634*1000
mass in gram = 83634 g
Now let us find the volume
We know that density = mass/volume
volume = mass/density
volume = 83634/1.84
volume = 45453.26 cm^3
Convert cm^3 to litres
Volume in litres = 45453.26 /1000
Volume in litres = 45.45 Litres
Convert from Litres to Gallons
1 gallon = 3.79 L
x gallons = 45.45 L
x = 45.45/3.79
x gallons = 11.99 L
Approx = 12 Litres
