Answer: 1169.298 L
Explanation: In order to go from grams to liters, you must find the moles first using the molar mass, 62.068 g/mol (found via google search). I will assume the ethylene glycol is in gas form so we can use the 22.4 L per mol conversion.
Using dimensional analysis, starting with the kg, we must convert to grams, then moles, then liters.
![\frac{3.24 kg}{} * \frac{1000g}{1 kg} * \frac{1 mol}{62.068 g} * \frac{22.4 L}{1 mol}](https://tex.z-dn.net/?f=%5Cfrac%7B3.24%20kg%7D%7B%7D%20%2A%20%5Cfrac%7B1000g%7D%7B1%20kg%7D%20%20%2A%20%5Cfrac%7B1%20mol%7D%7B62.068%20g%7D%20%2A%20%5Cfrac%7B22.4%20L%7D%7B1%20mol%7D)
Multiply the top individually, then the bottom individually.
![\frac{72576}{62.068}](https://tex.z-dn.net/?f=%5Cfrac%7B72576%7D%7B62.068%7D)
Divide out.
![= 1169.298 L](https://tex.z-dn.net/?f=%3D%201169.298%20L)
In the end, we get 1169.298 L of ethylene glycol.
Answer:
The P-H bonds are more polar than the N-H bonds.
Explanation:
Phosphine is a polar molecule with non-polar bonds. The phosphorus atom is bonded to three hydrogen atoms and the phosphorus atom has a lone pair of electrons. Since hydrogen and phosphorus are equal in electronegativity, it implies that they attract the shared pairs of electrons the same amount,hence bonding electrons are shared equally making the covalent bonds non-polar.
The lone pair of electrons on phosphorus causes the molecule to be asymmetrical with respect to charge distribution this is why the molecule is polar even though the are non-polar bonds in the molecule.
Looking at the values of electro negativity stated in the question, one can easily see that the difference in electro negativity between nitrogen and hydrogen is 0.9 while the difference in electro negativity between phosphorus and hydrogen is zero. It is clear that NH3 is naturally more polar than PH3 since each individual N-H bond in NH3 is a polar bond while the individual P-H bonds in PH3 are nonpolar.
M = n / V
M = 0.5 / 0.05
M = 10 mol/L-1
