How many moles are in 7950 g of CO2? ( pleas show calculation)

1 answer:

6 0

Answer:

Calculate the number of moles of CO2 by the formula n=PV/RT, where P is the pressure from Step 3, V is the volume from Step 2, T is the temperature from Step 1 and R is a proportionality constant equal to 0.0821 L atm / K mol.

The overall energy involved in the formation of CsCl from Cs(s) and Cl2(g) is −443 kJ mol−1. Given the following information: he

Alex17521 [72]

Explanation:

It is given that total energy is -443 kJ/mol and formula to calculate the lattice energy is as follows.

Total energy = heat of sublimation + bond dissociation energies + ionization energy for Cs + EA of $Cl^{-}$ + lattice energy

-443 kJ/mol = 76 + 121 + 376 - 349 + Lattice energy

Lattice energy = (-443 - 76 -121 - 376 + 349) kJ

Lattice energy = -667 kJ

Therefore, we can conclude that -667 kJ is the magnitude of the lattice energy for CsCl.
