d, about 3 kg of carbon dioxide is Together, Americans drive about 5.0 x 109 miles per day, and their cars get an average of 22 miles per gallon of gas used. For each kilogram of gasoline use produced. How many kilograms of COz are emitted into the atmosphere by cars in the US each day? [1 gal = 3.5 kg] Hint :- 1 mile = 1609 m Mass of coz = 5.0 *109 miles /1 gallon/ 22 miles X 3.5Kg gasoline/1 gallon X 3 kg co2 /1kg gasoline Select one: O a. 2 x 109 kg O b. 2.4 x 109 kg O c. 8.3 x 109 kg O d. 1.6 x 109 kg O e. None of the above

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
