Why do we use an objects mass, rather than its weight, to indicate the amount of matter it contains?
You go to a convenience store to buy candy and find the owner to be rather odd. He allows you to buy pieces only in multiples of tour, and to buy four, you need $0.23. He allows you only to use 3 pennies and 2 dimes. You have a bunch of pennies and dimes, and instead of counting them, you decide to weigh them. You have 636.3 g of pennies, and each penny weighs an average of 3.03 g. Each dime weighs an average of 2.29 g. Each piece of candy weighs an average of 10.23 g. How many pennies do you have? How many dimes do you need to buy as much candy as possible? How much would all of your dimes weigh? How many pieces of candy could you buy (based on the number of dimes from part b)? How much would this candy weigh? How many pieces of candy could you buy with twice as many dimes?
A(n) always has the same composition.
This year, like many past years, you begin to feel very sleepy alter eating a large helping of Thanksgiving turkey. Some people attribute this sleepiness to the presence of the amino acid tryptophan in turkey. Tryptophan can be used by the body to produce serotonin, which can calm the brains activity and help to bring on sleep. a. What mass in grams of tryptophan is in a 0.25-lb serving of turkey? (Assume tryptophan accounts for 1.0% of the turkey mass.) b. What mass in grams of tryptophan is in 0.25 quart of milk? (Assume tryptophan accounts for 2.0% of milk by mass and that the density of milk is 1.04 kg/L.)
