Question:

Determine whether the statement is true or false. Correct the statement to make it true if it is false.: "mmole" is a ratio of mmoles per liter of total solution

Ratios:

A ratio is the dividing of one property by another property. If the two properties are of the same kind - for instance, mass and mass or number of moles and number of moles - the ratio is unitless as the units of the two properties cancel each other. However, if the two properties are of different kinds, the ratio has a unit.

Answer and Explanation: 1

The statement is false. Mmole is a unit of the number of moles of substance present. The unit of mmole means millimole, which means the thousandth of a mole. So mmole is a variation of the unit mol that uses the metric system to express a smaller unit than the mole. This is useful when describing a very small quantity of a substance in moles. That way, the magnitude of the number of moles can be expressed in normal notations instead of a decimal with many zeros. For example, 0.0500mol can be expressed as 50.0 mmol.
