There are 24 protons in Chromium. You get the number of neutrons by subtracting the number of protons from the mass number which is the total number of protons and neutrons. Chromium's mass number is 52. You would subtract 24 from 52. 52-24=28. There are 28 neutrons in chromium.
Answer: The vapor pressure of Fe at is 465 mm Hg
Explanation:
The vapor pressure is determined by Clausius Clapeyron equation:
where,
= initial pressure at = 400 mm Hg
= final pressure at = ?
= enthalpy of vaporisation = 351 kJ/mol = 351000 J/mol
R = gas constant = 8.314 J/mole.K
= initial temperature = 2890 K
= final temperature = 2920 K
Now put all the given values in this formula, we get
Thus the vapor pressure of Fe at is 465 mm Hg
