How many grams are in 2.5 moles of Carbon
Jet001 [13]
According to the periodic table, carbon's molar mass is 12.011 grams per mole (that's the small number under the element).  So, just multiply like this to get the answer:

(2.5\ mol\ C)(\frac{grams\ C}{12.011\ mol\ C})=0.20814\ g\ C

So, there are approximately 0.208 grams in 2.5 moles of carbon.

Calculate the standard cell potential at 25 ∘c for the reaction x(s)+2y+(aq)→x2+(aq)+2y(s) where δh∘ = -793 kj and δs∘ = -319 j/
QveST [7]
First we will calculate free energy change:
ΔG₀ = ΔH₀ - (T * ΔS₀)
        = - 793 kJ - (298 * - 0.319 kJ/K) = - 698 kJ
We know the relation between free energy change and cell potential is:
ΔG₀ = - n F E⁰ where
F = Faraday's constant = 96485 C/mol
n = 2 (given by equation that the electrons involved is 2)
ΔG₀ = - 2 x 96485 x E⁰
- 698 kJ = - 2 x 96485 x E⁰
E⁰ = (698 x 1000) / (2 x 96485) = 3.62 volts
