- When I was recently living in Germany, the cost of gasoline was about 1.60 euro per liter. The most I could pump to fill up the empty tank on my VW Golf was 50.00 euro worth of gas at a time, after which amount the gas pump would shut off. This 50.00 euro worth of gas would last for about 190 km. (A) Given that the currency exchange rate was $1.00 = 1.12 euro, what was the cost of gasoline in dollars per gallon? (B) What was my gas mileage (fuel efficiency) in miles per gallon? All work must be shown , labeled , and explained in detail to receive credit. Note that where applicable, superscripts (X 2 ) can be written as X^2 and subscripts (X 2 ) can be written as X_2 if it saves you time.
- Theoretically speaking, how many moles of lithium bromide can be produced if we react 9.1 moles of CaBr 2 and 5.7 moles of LiCl? Reaction: CaBr 2 + 2LiCl → 2LiBr + CaCl 2 . You must show all work clearly and in detail to receive credit. All numbers seen immediately following the elemental symbols are intended to be subscripts.
- I cook my pasta by putting a little salt in the boiling water. If my pasta water is a 2.90% NaCl solution by mass with a density of 1.21 g/mL, how many mL of my pasta water contains 2.00 g of sodium? You must show all work clearly and in detail to receive credit. All numbers seen immediately following the elemental symbols are intended to be subscripts.
