A hydrate [hydrates have the general formula AB • xH2O] is found to have the percent composition: Na = 19.17%, C = 10.00%, H = 4.17% and O = 66.6%. After heating to 100 oC to drive off the water of hydration, the percent composition is found to be: Na = 27.38%, C = 14.28%, H = 1.19% and O = 57.15%. From this data, determine the probable molecular formula for the hydrate if the molecular weight = 120 amu.

A hydrate [hydrates have the general formula AB • xH2O] is found to have the percent
composition: Na = 19.17%, C = 10.00%, H = 4.17% and O = 66.6%. After heating to 100 oC to
drive off the water of hydration, the percent composition is found to be: Na = 27.38%,
C = 14.28%, H = 1.19% and O = 57.15%. From this data, determine the probable molecular
formula for the hydrate if the molecular weight = 120 amu.
