In the Q value formula, what do M1 and M2 represent?

• A. Mass of inner packaging
• B. Min net quantities per package
• C. The maximum net quantities allowed per package of dangerous goods
• D. The molar mass of substances

Answer: (C)

The Q value is used to determine whether the quantity in a package meets the allowable limits for dangerous goods. In this formula, M1 and M2 are the maximum net quantities allowed per package for the two parts of the packaging configuration involved in the calculation. They set the upper limits that, when substituted into the Q value equation, establish the threshold for compliance with the quantity restrictions. They are not the mass of inner packaging, not minimum quantities, and not the molar mass of substances.
