How many grams of solid sodium carbonate (Na2CO3, 105.99 g/mol) would be required to neutralize L of 1.0 M HCl? 

Your great uncle borrows your brand-new Chevrolet Camero v6 which typically holds around 19 gallons of gasoline. Pretending that this is 100% octane (114.23 g/mol) and that this volume of gas equates to 27×103 grams of octane. How much CO2 (in kg; 44.01g/mol) is produced when he empties your tank? (2 sig figs) 2C8H18 + 25 O2 —-> 16 CO2 + 18 H2O      

Tetraphosphorus hexaoxide (MW=219.9 g/mol) is formed by the reaction of phosphorus with oxygen gas. If a mixture of g of phosphorus (123.88 g/mol) produces g or P4O6, what is the percent yield for the reaction?  P4(s) + 3O2(s) —–> P4O6(s)    

Suppose you are hired to determine the true average amount of money that college students make while working on-campus jobs. If you want to be 95% confident that you are within $100 of the actual value, how many students would you need to survey? Assume that the true standard deviation is $600.  Reminder: It’s impossible to survey a fraction of a college student.
