(show all dimensional analysis)
1. 200.0 g is equivalent to how many pounds?
(*hint: first, convert grams to kg because the conversion factor given is in kg to lb)
The set up: 2.00gx (1kg/1000g)x (1lb/0.454kg) then, all the units cancel except for lb.
Since the least number of sig fig is 4- in the starting point- your answer must be in 4 s.f.
2. A 10.0 Km race is how many miles?
(*hint: the conversion rate isn't given to you on the bottom...but from today's exercise you know that 2.54 cm is equal to 1in. So, first convert km in terms of cm, then find in terms of miles like so)
The set up: 10.0km x (10,000cm/1km) x (1in/2.54cm) x (1ft/12in) x (1 mile/5280ft) all units cancel out except for miles.
Since the beginning number has 3 sig fig, round to 3 sig fig. (because 1 ft to 12 in is like saying 1 ft exactly (counting) to 12 inches exactly (counting) and they have infinite number of decimals-- if you are converting from the SAME system of unit, they can have infinite number of zeros because those are exact conversions.
------------------------------------------------------------------------------------------
1 inch = 2.54 cm
1 quart = 0.9463 L
1 ounce = 28.35 g
5280 feet = 1 mile
4 quarts = 1 gallon
1 pound = 0.454 Kg
1 yard = 3 feet = 36 inches
32 ounces = 1 quart
16 ounces = 1 pound

Alright, agents...to get to your next station (station 1* If you haven't done so already), you must go from Ms. Isabell's door (go inside, face the window, look to left 45.44cm)
Good luck!
