Statements: (1) The conversion factor 10³ m/1 km contains an unlimited number of significant figures.
(2) Density may be used as a conversion factor to convert from mass to volume.
(3) The equation 2.33 lb = 625 g is a correct mathematical statement.

Question

Quizplus · Accepted Answer

(1) is not true as conversion factors have a finite number of significant figures, typically determined by the precision of the measurements involved.
(2) is true as density is defined as mass per unit volume, which can be rearranged to give volume per unit mass, and therefore can be used as a conversion factor between the two. 
(3) is not true as 2.33 lbs and 625 g are not equal.
