What volume of a 1.50 M KBr solution contains 0.555 mol of KBr?

1. Rearranging the molarity definition, volume equals moles divided by molarity. 2. Substituting gives 0.555 mol / 1.50 mol/L. 3. The division yields 0.370 L of solution. 4. Units check: mol divided by mol per litre leaves litres. 5. The value 0.833 L multiplies the two numbers instead of dividing, and 2.70 L inverts the ratio. _Source: OpenStax Chemistry (CC BY 4.0), Ch 3 "Composition of Substances and Solutions", section 3.3 Molarity_
