The density of helium gas is 0.861 g/L, what is this value in lb/mL? 13. The speed of light is 299792458 m/s, what is this in furlongs/fortnight? (1 furlong - 220 yards, and 1 fortnight - 14 days) 14. How many chopsticks does it require to eat 22 ducks? Assume that 2 ducks feed 7 people & each person needs 3.2 chopsticks. 15. The density of the sun is 1.410 x 10 kg/m'. What is this in tons/mi? 16. A solution of barium nitrate has 61.2 g of barium nitrate in 1 liter of solution. How many mg of barium are there in exactly 7.5 quarts? 17. Suppose on average 2 penguins have 750000 feathers between them, 1 pillow requires 1283 feathers, 3 hippies need 16 pillows total to sleep, a treehouse can fit 8 hippies, and you need 322 planks of wood to build a treehouse. However, the hippies require that the wood for the treehouses be from recycled bongos, which will give you 5 planks of wood each. If you have 46 penguins, how many bongos do you need? 18. A patient is receiving 30 mL/hr IV drip of an antibiotic. If the bag contains 1 g of compound in 500 mL of solution, how much drug is the patient receiving in 53 minutes? 19.

What is the maximum safe dose for the patient to take? 20. While prospecting in the woods, you find a solid gold nugget. You don't have a scale to weigh it, but you remember that the density of gold is 19.2 g/mL. You measure the volume of the cylinder to be 7.4 mL. What is the mass of the nugget?
