A student mixed 75g of Nitric Acid(HNO3) with water to prepare1.5L of solution. What is the molarity of the solution?

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.

The number of moles of a given mass of a substance can be found without knowing its molecular formula or molar mass. true false
