A fictitious element X has an average atomic mass of 122.118 u. Element X has two naturally occuring isotopes. The most abundant isotope has an isotopic mass of 121.624 u and a relative abundance of 66.16%. Calculate the isotopic mass of the least abundant isotope.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

give me abc and i will get it for u.
