Lesson: Units and Equations Chemistry

Students will be able to

• know that SI units are the standard units of measurement,
• identify SI units and derived units with chemical applications,
• recognize the different prefixes that are used for quantities and identify the size of a value from them (e.g., nano, micro, milli, kilo, mega),
• convert between units (e.g., g to kg, km to m, cm³ to m³),
• explain the cancellation of units in dimensional analysis (e.g., g/(g/mol) = mol in n = m/M),
• use the units of variables in a calculation to determine the units of the answer,
• rearrange simple algebraic equations to change the subject of the equation,
• solve simple algebraic equations (related to chemistry).
