Carbon dioxide emissions associated with a one-night stay in a hotel room are calculated at 28.98 kg of CO2 per room day for an average hotel. The 250 rooms of your hotel are all occupied for two days during a college football game. How much CO2 did the guests and hotel release into the atmosphere? Round your answer to the nearest whole number.

10.4 mL of ethanol is allowed to undergo combustion with an excess of gaseous oxygen to produce carbon dioxide and water vapor.  What mass of carbon dioxide will be produced from this combustion?  The density of ethanol (C2H6O) is 0.789 g/mL. (3 sf)

Aqueous hydrobromic acid HBr reacts with solid sodium hydroxide NaOH to produce aqueous sodium bromide NaBr and liquid water H2O . If 1.82g of water is produced from the reaction of 15.4g of hydrobromic acid and 10.0g of sodium hydroxide, calculate the percent yield of water. Be sure your answer has the correct number of significant digits in it.

A major component of honey is fructose (C6H12O6) with a molar mass of 180.16 g/mol. A tablespoon (15.0 mL) of honey is considered one serving. How many tablespoons must be eaten to consume 0.1900 moles of fructose? Assume honey is 100% fructose. The density of honey is 1.45 g/mL.

The chemical formula for t-butanol is: (CH3)₂COH Calculate the molar mass of t-butanol. Round your answer to 2 decimal places. g g*mol x10 X 5

Soda ash (sodium carbonate) is widely used in the manufacture of glass.  Prior to the environmental movement much of it was produced by the following reaction.   CaCO3 + 2 NaCl → Na2CO3 + CaCl2   Unfortunately, the byproduct calcium chloride is of little use and was dumped into rivers, creating a pollution problem.  As a result of the environmental movement, all of these plants closed.  Assume that 125g of calcium carbonate (100.09 g/mol) and 125 g of sodium chloride (58.44 g/mol) are allowed to react.   Determine how many grams of useful sodium carbonate (105.99 g/mol) will be produced.  How many grams of useless calcium chloride (110.98 g/mol) will be produced?  You should also determine how many grams of excess reactants are left (indicate which one is the limiting reactant)
