Unformatted text preview: o F. Express this temperature in degrees Celsius and Kelvin. (Hint: use that ( o F - 32) x 5/9 = o C and that o C + 273.15 = K) 3) Solving problems with dimensional analysis: a) The density of a liquid is 0.821 g/mL. What is the volume of 71.3 g of this liquid? b) How many seconds are there in one week? c) A radio wave travels 186,000 miles per second. How many kilometers will the wave travel in one microsecond? (Hint: use the fact that 1 mile = 1.61 km) d) If a car goes 30.0 miles per gallon of gasoline, how many kilometers could it travel on 1 liter of gasoline? (Hint: use the hint from c) along with the fact that there are 4 quarts per gallon and that 1 L = 1.06 qt)...
