A certain drug dosage calls for 284 mg per kg per day and is divided into four doses (1 every 6 hours). If a person weighs 215 pounds, how many milligrams of the drug should he receive every 6 hours? Round your answer to the nearest milligram. Do not include units with your answer. Question 14 4 pts If a truck averages 16 miles to the gallon, how many pounds of carbon dioxide are emitted into the atmosphere when the...
The corporate average fuel economy (CAFE) standard for mileage is currently 26.5 miles per gallon of gasoline (the defender) for passenger cars. To conserve fuel and reduce air pollution, suppose the u.s Congress sets the CAFE standard at 35 miles per gallon(the challenger) in 2010. An auto will emit on average 0.8 pounds of carbon dioxide(c02) per mile driven at 26.5 miles per gallon, and will emit 0.65 pounds of CO2 per mile driven at 35 miles per gallon. A....
Americans drive about 4.0 x 10^9 miles per day, and their cars get an average of 20 miles per gallon of gas used. For each kilogram of gasoline used, about 3 kg of carbon dioxide is produced. How many kilograms of CO2 are emitted into the atmosphere by cars in the US each day? [1 gal = 3.5 kg]
Your car gets 33 miles per gallon, you drive an average speed of 44 miles per hour. How much gas do you use in an hour?33/44? or 44/33
Americans combined drive about 4.0 x 109 miles per day and their vehicles get an average of 20 miles per gallon of fuel used, which is the hydrocarbon octane (C8H18). a) write a balance equation for the oxidation of octane b) then for each 1kg of gasoline that is burned, calculate how many kg of carbon dioxide are produced. c) how mnay kilograms of CO2 are emitted into the atmosphere each day by cars in the U.S? The density of...
If one gallon of gasoline contains about 2.0 g of lead, how much lead (in kg) is emitted into the atmosphere from a car that travels 10,000. miles a year and averages 25 miles per gallon of gasoline?
A compact car gets 31.4 miles per gallon on the highway. If gasoline contains 65.9% carbon by mass and has a density of 0.7355 g/mL, determine the mass (in kg) of carbon dioxide produced during a 500. mile trip.
Suppose the car (van, SUV) you drive gets 25 miles/gallon. If you drive 19,000 miles per year how many tons of the green house gas CO2 are you releasing each year? Assume your fuel is octane (C8H18) and the combustion reaction is balanced: C8H18 + 12.5 O2 → 8 CO2 + 9 H2O Addition information: Density of octane = 0.700 g/mL 1 gallon = 3785 mL 1 pound = 454 g 1 ton = 2000 lbs
Suppose that gasoline costs $3.55 per gallon. Your car gets 35 miles per gallon. How many gallons of gas do you need to drive 455 miles? How much will gasoline cost to drive 1000 miles? How many miles can you drive on 19 gallons of gas? How far can you drive on $15 worth of gas?
Assume you own a car that gets 20 miles per gallon on average. If you typically drive 16,000 miles per year and the price of gasoline goes from $2.00 per gallon to $3.00 per gallon, what is your additional cost per year?
