Calculate the amount of energy required to increase the temperature of 18.0 go vapor water from 275.0 degrees * C to 385 degrees
1 answer:
Answer:
<u>The amount of energy required to increase temperature 275°C to 385°C is ΔQ =3.95208kJ</u>
Explanation:
Given :
- <em>The mass of the water vapour is 18 g</em>
- <em>The initial temperature : 275°C</em>
- <em>The final temperature : 385°C</em>
According to the formula :
ΔΔ
Where ,
- <em>Δ
is the heat supplied</em>
- <em>
is the mass of the substance (water vapour) = 18g</em>
- <em>
is the specific heat of the substance ( water vapour) =
</em>
- <em>Δ
is the change in temperature =
</em>
∴
ΔQ =
⇒ΔQ =3.95208kJ

To plot the calibration curve, you need to prepare iron solutions with known concentrations and measure their absorbance. You need to pipet 0 mL of the diluted solution to have 0.00 mg of iron.
In spectrophotometry, to plot the calibration curve, you need to prepare solutions with known concentrations and measure their absorbance.
We have a standard iron solution with a concentration of 0.2500g/L of pure iron (C₁). We pipet 25.00mL (V₁) of this standard iron solution into a 500mL (V₂) volumetric flask and dilute up to the mark with distilled water.
We can calculate the concentration of the diluted solution (C₂) using the dilution rule.
Then, if we wanted to prepare the blank, that is, the solution that contains the same matrix but not the analyte, and whose concentration in iron is 0.00 mg/L, we wouldn't pipet any of the diluted solution.
