Dimethylglyoxime (DMG) reacts with nickel(II) ion in aqueous solution to form a bright red compound. However, DMG is insoluble in water. To get it into aqueous solution where it can encounter $Ni^{2 +}$ ions, it must first be dissolved in a suitable solvent, such as ethanol. Suppose you dissolve $45.0 g$ DMG $(C_{4} H_{8} N_{2} O_{2})$ in $500. mL$ ethanol $(C_{2} H_{5} OH;$ density $= 0.7893 g / mL) .$ Determine the molalityand weight percent of DMG in this solution.
