Calculate the average atomic mass of magnesium using the following data for three magnesium isotopes. (Abundance not in percentage form)
Isotope=(Mg-24, Mg-25, Mg26), Mass(amu)=(23.985, 24.986, 25.983) & Relative abundance=(0.7870, 0.1013, 0.1117
Consider the following reaction
2A(g) + B(g) ⇋ C(g)
A mixture containing 1.0 mole of A and 0.75 mole of B is left to attain equilibrium in a 1.0
dm3 flask at 65oC. The equilibrium mixture is found to contain 0.7 moles of A and 0.6 moles of B. Calculate Kc at 65oC.
