Answer:
1.7 × 10 ^42
Explanation:
Using Nernst equation
E°cell = RT/nF Inq
at equilibrium
Q=K
E°cell = 0.0257 /n Ink= 0.0592/n log K
Fe2+(aq)+2e−→Fe(s) E∘= −0.45 V
Ag+aq)+e−→Ag(s) E∘= 0.80 V
Fe(s)+2Ag+(aq)→Fe2+(aq)+2Ag(s)
balance the reaction
Fe → Fe²⁺ + 2e⁻ reversing for oxidation E° = 0.45 v
2 Ag⁺ +2e⁻ → 2Ag
n = 2 moles and K = equilibrium constant
E° cell = 0.80 + 0.45 = 1.25 V
E° cell = (0.0592 / n) log K
substitute the value into the equations and solve for K
(1.25 × 2) / 0.0592 = log K
42.23 = log K
k = 10^ 42.23
K = 1.7 × 10 ^42
By the process of Nuclear Fission:
1) We Generate Electricity. - If the process is controlled, then we can do this. It's very better way to generate electricity. 'cause of it's many advantages, all nation wants to enhance their electricity production through this mean.
2) We Create explosive. - Again, with the help of nuclear fission we can create certain helpful bombs like Atom Bomb which will help us in war.
Hope this helps!

Answer:
See the explanation and examples below, please.
Explanation:
To calculate the molar mass of a substance you must have the atomic weights of each component:
Example NaCl ionic compound (sodium chloride, known as table salt)
Molar mass NaCl = Atomic weight Na + Atomic weight Cl = 22, 98 gr + 35, 45gr = 58.35 grams / mol
Example covalent compound HCl (hydrochloric acid) = Atomic weight H + Atomic weight Cl = 1, 004gr + 35, 45 gr = 36, 45 grams / mol
In the case of having compound H20 (water), it is calculated:
Molar mass NaCl = 2 x (Atomic weight H) + Atomic weight 0 (the atomic weight of 1 mol of Hydrogen is multiplied by 2)
