Answer:
The answer to your question is V₁ = 12.5 ml
Explanation:
Data
Volume = V₁?
[NaOH] = C₁ = 4.0 M
Volume 2 = V₂ = 100 ml
[NaOH] = C₂ = 0.5 M
Formula of dilution
V₁C₁ = V₂C₂
Solve for V₁ (original solution)
V₁ =
Substitution
V₁ =
Simplification
V₁ =
Result
V₁ = 12.5 ml
The specific heat capacity of this chunk of metal is equal to 0.32 J/g°C.
<u>Given the following data:</u>
- Mass of metal = 250g
- Quantity of energy = 400 Joules
- Initial temperature = 20°C
- Final temperature = 20°C
To determine the specific heat capacity of this chunk of metal:
<h3>The formula for quantity of heat.</h3>Mathematically, quantity of heat is given by the formula;
<u>Where:</u>
- Q represents the quantity of heat.
- m represents the mass of an object.
- c represents the specific heat capacity.
- ∅ represents the change in temperature.
Making c the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Specific heat, c = 0.32 J/g°C.
