Tea sweetened to a sucrose molarity of 0.05 M is poured out. What volume of the tea holds 0.004 mol of sucrose?

1. Molarity is moles of solute per litre of solution, so volume equals moles divided by molarity. 2. Substituting gives 0.004 mol / 0.05 mol/L = 0.080 L. 3. Converting to millilitres gives 80 mL of tea. 4. The value 12.5 mL comes from dividing the molarity by the moles, which inverts the ratio. 5. The values 8.0 mL and 200 mL are single decimal place slips in either direction. _Source: OpenStax Chemistry (CC BY 4.0), Ch 3 "Composition of Substances and Solutions", section 3.3 Molarity_
