Document Summary
For length, the basic unit is the meter (m). For mass, the basic unit is the gram (g). For volume, the basic unit is the liter (l). Exponential notation kilo- base unit centi- milli- micro- nano- k- no prefix c- m- n- Dimensional analysis is a written method of converting between different units of measurement. Molarity refers to the number of moles of solute per 1 liter of solution.

Suppose you need to prepare a 4% sodium chloride solution. This is made by dissolving 4 g of nacl in distilled water, up to a total volume of 100 ml. A 70% ethanol solution is made by mixing 70 ml of absolute (100%) ethanol with 30 ml of distilled water, creating a solution with a final volume of 100 ml.
