c. three significant figures _480. or 4.80 x 102_
d. four significant figures 480.0_or 4.800 x 102
5. Report to the proper number of significant figures: (6.404 x 2.91)/(18.7 – 17.1) = _ 12_____
6. Use the following exact conversion factors to perform the stated calculations:
5 ½ yards = 1 rod
40 rods = 1 furlong
8 furlongs = 1 mile
a. The Kentucky Derby race is 1.25 miles. How long is the race in rods, furlongs, meters, & kilometers?
400 rods
10 furlongs
2012.5 meters
2.01 km
b. A marathon race is 26 miles, 385 yards. What is this distance in rods, furlongs, meters, & kilometers?
26.22 miles
8384 rods
209.6 furlongs
42 182 meters
42.2 km
7. A material will float on the surface of a liquid if the material has a density less than that of the liquid.
Given that the density of water is approximately 1.0 g/mL, will a block of material having a volume of
1.2 x 104 in3 and weighing 350 lb float or sink when placed in a reservoir of water?
Material Density < Water Density
0.81 g/mL < 1 g/mL
Result: FLOAT
8. A 25.00 g sample of a solid is placed in a graduated cylinder and then the cylinder is filled to the 50.0 mL
mark with benzene. The mass of benzene and solid together is 58.80 g. Assuming that the solid is
insoluble in benzene and that the density of benzene is 0.880 g/cm 3, calculate the density of the solid.
Mass SOLID = 25.00 g
1) Solve for Benzene volume
Mass BENZENE = 33.8 g
Density BENZENE = 0.88 g/cm3
2) Solve for Solid volume
3) Solve for Density of Solid
2.16 g/mL
