Quantitative Transfer simply means that all the material to be transferred from one place
to another must make the trip. For example, every particle of solid must be transferred
from the weighing paper to the (clean) beaker.
This can be done be carefully tipping the creased weighing paper to pour the solid into the
beaker. Tapping the paper with a spatula will knock particles into the beaker.
Finally, the paper should be rinsed into the beaker, to remove all traces of the solid.
