The specific heat capacity of ethanol is 2.46 joules per gram.
Now, we may use the equation:
Energy = mass * specific heat capacity * change in temperature
Here we may substitute:
mass = density * volume
Energy = density * volume * specific heat capacity * change in temperature
720 = 0.789 * 35 * 2.46 * ΔT
ΔT = 10.6
The final temperature will be
20 + 10.6
= 30.6 °C
1. write the conversion as a fraction (that equals 1)
2. Multiply it out (leaving all units in the answer)
3. Cancel any units that are both top and bottom<span />
Answer:

Explanation:
Considering:
Given :
For NaOH :
Molarity = 0.0500 M
Volume = 45.88 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 45.88×10⁻³ L

Moles of NaOH = Moles of monoprotic acid
So, moles of monoprotic acid = 0.002294 moles
Given that:- mass = 0.456 g
The formula for the calculation of moles is shown below:
Thus,

The most important source of error in the measurement of CO2 elimination is rebreathing, which corresponds to bout 24 ml of end expiratory gas per breath with the standard Y-pieces and tubing.This problem may be decreased by the use of non-return valves in the Y-pieces.
