Explanation:
Equation for the given reaction is as follows.
Therefore, moles of NaOH and HA are calculated as follows.
Moles of NaOH = 
= 
= 0.00864 mol
Moles of HA = 0.00864
Also, moles = 
Molecular weight = 
= 122.22 g/mol
Thus, we can conclude that molar mass of given unknown organic acid is 122.22 g/mol.
Answer:
Because the compound has a formula of M2O, the number of valence electrons of M should be 1. Therefore, (1) Group 1 is the correct answer because elements in group 1 have 1 valence electron.

The main points of Dalton's atomic theory, as it eventually developed, are: Elements are made of extremely small particles called atoms. Atoms of a given element are identical in size, mass and other properties; atoms of different elements differ in size, mass and other properties.
