Explanation:
Relation between molarity and molar mass is as follows.
Molarity = 
It is given that mass is 1 mg/ml which is also equal to 
g.
Molecular mass = 58 Da = 58 g/mol
Volume = 1 ml
Therefore, calculate molarity as follows.
Molarity =
= 
= 0.0172 molar
It is known that 1 molar equals 1000 millimolar.
So, 0.0172 molar = 
= 17.2 millimolar
Thus, we can conclude that the concentration of given solution is 17.2 millimolar.

Answer:
A nonspontaneous process
Explanation:
The spontaneity of a reaction is given by the standard Gibbs free energy (ΔG°). We can calculate ΔG° using the following expression.
ΔG° = ∑np . ΔG°f(p) - ∑nr . ΔG°f(r)
where,
ni are the moles of reactants and products
ΔG°f(p) are the standard Gibbs free energies of formation of reactants and products
For the equation,
CO₂(g) → CO₂(aq)
ΔG° = 1 mol × ΔG°f(CO₂(aq)) - 1 mol × ΔG°f(CO₂(g))
ΔG° = 1 mol × (-386.0 kJ/mol) - 1 mol × (-394.4 kJ/mol)
ΔG° = 8.4 kJ
By convention, ΔG° > 0 means that the reaction is nonspontaneous.
The empirical formula CH₂O has a mass [(12 × 1) + (1 × 2) + (16 × 1)] = 30 g/mol
If the empirical formula is 30 g/mol,
and the molecular formula is 60 g/mol
Then the multiple is = 60 g/mol ÷ 30 g/mol
= 2
Therefor the molecular formula is 2(CH₂O) = C₂H₄O₂ (OPTION 2)
The groups on the periodic table are arranged by valence electron number. (Ex. Group 2 has 2 valence electrons in the electron configuration
