ould you help me with all three, please 8) If the solubility limit of sodium acetate (Molar mass-82 g/mol) at room temp is 76 grams per 100 grams of water, would a solution where 355 grams of sodium acetate is dissolved in 465 mi of water be considered supersaturated7 Show all your work, and asume 1 mi water-1gram 9) if the s Am isotope emits an alpha particle, what would be the atomic namber of the 243 resulting daughter atom?...
please answer and explain
thanks
