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

If 1.8 l of water is added to 2.5l of a 7.0 molarity koh solution, what is the molarity of the new solution

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
