Answer and Step-by-step explanation:
In the laboratory, the comparison between the experimental factor and the standard conversion factor of 454g/lb has to do with experiments that involves (non-aqueous, powdery or solid substances) which has the mathematical relationship as:
As 1 grain = 1.43 x 10^-4 lb
1 lb = 454 g
Therefore 1 lb = 454 g can be used as standard conversion factor for comparing experimental factors.
