please answer the second question (on the bottom of the page)

Global Anthropogenic CO, Emissions 2010 The main source of anthropogenic (human made) carbon dioxide is from burning fossil fuels. We will calculate the amount of CO added by the burning of the three major fuels shown in the graph at right. Let's start with petroleum: Petroleum-34.4% Natural Gas- 19.5% Coal-41.6% Cement Production-4.9% Land Use and Land Cover Change-10.9% According to the International Energy Agency: How much oil is there in a barrel? A barrel of oil is equal to 159 litres, 42 US gallons or 35 imperial gallons. How many barrels of oil are produced and consumed a day? For 2016, the IEA Oil Market Report forecasts worldwide average demand of nearly 96 million barrels of oil and liquid fuels per day - that works out to more than 35 billion barrels a year. Production breached 97 million barrels per day (mb/d) in late 2015, and Medium-Term Oil Market Report 2016 foresees demand crossing the 100 mb/d threshold towards the end of its five-year outlook period. Let's assume that oil is mostly octane, C3H8. If the density of oil is about 800g/L determine the mass of octane consumed per year in the world. Using gas stoichiometry, calculate the volume of carbon dioxide produced by burning petroleum per year. Assume the gas reaches the average surface temperature of the earth (15C) and standard atmospheric pressure. Show your work
