Answer:
Explanation:
Using Gay lussac's law equation as follows;
P1/T1 = P2/T2
Answer: Heat of vaporization is 41094 Joules
Explanation:
The vapor pressure is determined by Clausius Clapeyron equation:
where,
= initial pressure at 429 K = 760 torr
= final pressure at 415 K = 515 torr
= enthalpy of vaporisation = ?
R = gas constant = 8.314 J/mole.K
= initial temperature = 429 K
= final temperature = 515 K
Now put all the given values in this formula, we get
![\log (\frac{515}{760}=\frac{\Delta H}{2.303\times 8.314J/mole.K}[\frac{1}{429K}-\frac{1}{415K}]](https://tex.z-dn.net/?f=%5Clog%20%28%5Cfrac%7B515%7D%7B760%7D%3D%5Cfrac%7B%5CDelta%20H%7D%7B2.303%5Ctimes%208.314J%2Fmole.K%7D%5B%5Cfrac%7B1%7D%7B429K%7D-%5Cfrac%7B1%7D%7B415K%7D%5D)
Thus the heat of vaporization is 41094 Joules
<h3><u>Answer</u>;</h3>
19 mg
<h3><u>Explanation</u>;</h3>
dose = 5.0 mg/kg
weight of infant = 8.5 pounds
Convert 8.5 pounds to kg: 8.5 pounds = 3.86 kg
Therefore;
The dose to give the infant is:
= (5.0 mg/kg) x (3.86 kg)
= 19.3 mg
<u>≈ 19 mg</u>
