We are given that alcohol is the solute, which leaves whatever is not alcohol as the solvent. 20.0% of the solution’s mass is alcohol, meaning 80.0% of the solutions mass is solvent. We are given its mass as 170 g, so just multiply 0.800*170 g = 136 g.
2Ag +(aq) + SO4 2-(aq)------>Ag2SO4 (s)
Answer:
Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements.
Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature.
