Determine the normal boiling point given the critical point, triple point, and normal melting point. Critical point: 113.0 atm at 573 C

Triple point: 0.104 atm at 117 C

Normal melting point: 1 atm at 123 C

Normal boiling point: 1 atm at ? C

I tried using the clausius-clapeyron equation, the first time solving for delta H vaporization, then using that value to find Tbp. I tried using multiple combinations of the points, but I have yet to get the right answer. (So far, I've gotten 248, 123, and 1794). Help is appreciated!

Im not sure but if i figure it out i’ll hello you

    pb(so₄)₂this element is lead (iv) sulfate. lead is a multivalent ion. but we know that sulfate ions, so₄²⁻, have a charge of -2. in order to have the ratios match up, we need pb⁴⁺ (two times as many pb⁴⁺  than so₄²⁻).the molar mass can be calculated by finding the mass of one mole of this compound. consider the following calculation,  where amu represents the atomic mass unit. the amu for each atom involved in this compound can be found on a periodic table.  molar mass = amu pb + 2(amu s + 4 * amu o)from a periodic table (with masses rounded to the nearest tenth),      amu pb = 207.2 g    amu s =  32.1 g    amu o = 16.0 gtherefore    molar mass =  207.2 + 2(32.1 + 4*16.0) = 399.4 gthe molar mass is therefore 399.4 grams per mol
