Mortar bag mix.
Use a measured or already specified prepared mortar volume rather than guessing it from dry bag mass.
Read the right quantitative data
Mixed yield per complete bag for the selected preparation basis.
Check this ordering assumption
Subtracting the outer volume of hollow units from a wall can substantially misstate mortar demand.
Verify how the required joint or bed volume was obtained before converting to bags.
