Explanation:
Use "Dimensional Analysis" to determine what "conversion factors" you will need before you do the math.
We need a mass conversion unit (
Volume will take two steps -
NOW we can apply these to our specific example.
Explanation:
- Need to know the common equivalence statements that usually are printed at the back of the composition notebooks; i.e.,
#1kg=1000g#
#1kg=2.205lb#
#:. 1000g=2.205lb#
#1L=1000mL#
#1gal=3.785L# - Knowing these facts will also provide you the needed conversion factors to convert the density of water expressed in
#(g)/(ml)# to#(lb)/(gal)# as required.
#a. 1000g=2.205lb#
#(1000g)/(2.205lb) or color(red)((2.205lb)/(1000g)#
3. Either of the reflected values are the possible conversion factors, but careful analysis should be taken so that the desired units are obtained; i.e.,
