Explanation:
It is known that 1 gram contains 1000 milligrams. And, mathematically we can represent it as follows.
or
So, when we have to convert grams into milligrams then we simply multiply the digit with 1000. And, if we have to convert a digit from milligrams to grams then we simply divide it by 1000.
Answer:
<h2>The equilibrium constant Kc for this reaction is 19.4760</h2>Explanation:
The volume of vessel used= ml
Initial moles of NO= moles
Initial moles of H2= moles
Concentration of NO at equilibrium= M
Moles of NO at equilibrium=
= moles
2H2 (g) + 2NO(g) <—> 2H2O (g) + N2 (g)
<u>Initial</u> :1.3*10^-2 2.6*10^-2 0 0 moles
<u>Equilibrium</u>:1.3*10^-2 - x 2.6*10^-2-x x x/2 moles
∴
⇒
<u>Equilibrium</u>:0.31*10^-2 1.61*10^-2 0.99*10^-2 0.495*10^-2 moles
