The mass is 150,000 grams. Multiply 100 by 50 by 30 to determine the container's volume, which equals 150,000 cm^3. Since a milliliter is equivalent to one cubic centimeter, and given that the density of water is one gram per milliliter, it follows that the mass of water is 150,000 grams.
The balanced chemical equation for the neutralization of HCl with 
is:
Given weight of = 5g
Moles of = 
Volume of HCl solution = 
Assuming the density of the solution is 1.0 g/mL
Mass of HCl solution = 50 g
Overall mass of the solution = 50 g + 5 g = 55 g
To find the heat of neutralization, we calculate:
Q = m C ΔT
where m equals the mass of the solution = 55 g
C represents the specific heat capacity of the solution = 4.184
ΔT signifies the temperature change = 6.8 K = (6.8 - 273) C = -266.2
The enthalpy of neutralization per mole of
= 
Solution:
Washing Clothes & Dissolving Sugar
Clarification:
Consider each scenario:
1) For washing clothes, water is essential; without it, washing is ineffective.
2) Connecting brake pedals to brake pads requires solids, not liquids.
3) To deodorize a space, one would likely reach for an aerosol spray, which is a gas.
4) Sculpting involves solid tools and a solid medium.
5) Dissolving sugar necessitates a liquid to be effective!
6) While one might assert that paint is a liquid, it still might not fit the category; I would categorize this application as solid.
7) Gears employed in machinery are solid components!
