Gravitational pull coming from the sun
The answer is <span>ionic aluminum fluoride (</span>AlF3). Note that boiling points of pure solvents are raised in the presence of solutes. The type of solute also affects the boiling point elevation of the solution. Ionic substances tend to raise it more than covalent ones, so sucrose is out of the picture. Next, consider the number of ions the ionic substance produces. The more ions, the greater the BPE. AlF3 dissociates into 4 ions.
Hey there!
<span>Use the equation of Clapeyron:

T in kelvin :
26 + 273.15 => 299.15 K
R = 0.082
V = 10.2 L
P = 0.98 atm
number of moles :
P *V = n * R * T
0.98 * 10.2 = n * 0.082 * 299.15
9.996 = n * 24.5303
n = 9.996 / 24.5303
n = 0.4074 moles
Therefore:
Molar mass H2O = 18.01 g/mol
1 mole H2O ------------- 18.01 g
0.4074 moles ----------- m
m = 0.4074 * 18.01 / 1
m = 7.339 g of H2O
Explanation:
Intermolecular force s between particles in a matter holds particles of molecules together in substances.
- The stronger the intermolecular forces the more solid a substance is.
- The weakest intermolecular attraction are found in gases as they have negligible attractive forces in between their particles.
- Solids are held together by very strong attractive forces.
- Liquids have weak forces holding them in place and this allows for a little movement.
- Gases are typically have very weak to negligible attractive forces.
