Question

Help! I don't understand what this problem wants me to do:

Many labels give metric equivalents of English
quantities. Examples are 12 fluid ounces (9345.66
mL), 353 ft (107.59 m), 2.0 inch (50.80 mm).
Report each metric equivalent using the correct
number of significant digits.

Answer 1

its about converting the metric answer into the most logical expression. for the first one 9345.66 mL is the same as 9.34 liters. (1000mL = 1L) and then 2 spots after the decimal for the same sig figs.

Answer 2

It want you to express the metric equivalent to the same precision as the British measurement are quoted. example the 353 feet is quoted to one foot or .3 meters so how many significant figures would you use to express that quantity in meters without making it appear more accurate? the 107.59 suggests a precision of less than 1 cm ie 0.01meters but the British expression suggests the accuracy is less than a foot or 0.3 m. If you rounded the metric to 107.6 this still suggests a precision of 0.1m which is stll less than 0.3. Therefore you should round it up to the nearest meter or 108meters

Buy the way the first set of numbers is incorrect 12 fluid oz. is 354.90 ml

Answer 3

Even slightly less: it is 340 mL.
