Precious metals and gems are measured in troy weights in the English system:
24 grains 1 pennyweight (exact)
20 pennyweight = 1 troy ounce (exact)
12 troy ounces 1 troy pound (exact)
1 grain = 0.0648 g
1 carat = 0.200 g

- At sea, distances are measured in nautical miles and speeds are expressed in knots. 1 nautical mile =6076.12ft 1 knot =1 nautical mi/h (exactly) (a) How many miles are in one nautical mile? (b) How many meters are in one nautical mile? (c) A ship is traveling at a rate of 22 knots. Express the ship's speed in miles per hour.arrow_forwardA gasoline station in Manila, Philippines, charges 38.46 pesos per liter of unleaded gasoline at a time when one US. dollar (USD) buys 47.15 pesos (PHP). The car you are driving has a gas tank with a capacity of 14 U.S. gallons and gets 24 miles per gallon. (a) What is the cost of unleaded gasoline in Manila in USD per gallon? (b) How much would a tankful of unleaded gasoline for your car cost in USD? (c) Suppose that you have only PHP 1255 (a day's wage for an elementary school teacher) and the car's tank is almost empty. How many miles can you expect to drive if you spend all your money on gasoline?arrow_forwardFor a material to float on the surface of water, the material must have a density less than that of water (1.0 g/mL) and must not react with the water or dissolve in it. A spherical ball has a radius of 0.50 cm and weighs 2.0 g. Will (his ball float or sink when placed in water? (Note: Volume of a sphere=43r3 .)arrow_forward
- 1.48 A rock is placed on a balance and its mass is determined as 12.1 g. When the rock is then placed in a graduated cylinder that originally contains 11.3 mL of water, the new volume is roughly 17 rnL. How should the density of the rock be reported?arrow_forwardTwo students were assigned to determine the mass of a sample of an unknown liquid. Student A used an ordinary laboratory balance that could determine mass to ±0.01 g. Student B used an analytical balance that could measure mass to ±0.1 mg. Each made four measurements, giving the following results: Student A: 8.19 g, 8.22 g, 8.21 g, 8.25 g Student B: 8.2210 g, 8.2210 g, 8.2209 g, 8.2210 g 2. Which student is more precise? A Barrow_forwardAn empty beaker with a mass of 42.3 g is filled with a liquid, and the resulting mass of the liquid and the beaker is 62.87 g. The Volume of this liquid is 19 mL. What is the density of the liquid?arrow_forward
- Ultrapure silicon is used to make solid-state devices, such as computer chips. What is the mass of a circular cylinder of silicon that is 12.40 cm long and has a radius of 4.00 cm? The density of silicon is 2.33 g/cm3.arrow_forwardEthanol has a density of 0.789 g/cm3. What volume must be poured into a graduated cylinder to give 19.8 g of alcohol.arrow_forwardA student determines the density of a metal by taking two cylinders of equal mass and volume. Cylinder A is filled with mercury and the metal. The mercury and metal together have a mass of 92.60 g. Cylinder B is filled only with mercury. The mass of the mercury in cylinder B is 52.6 g more than the mass of mercury and metal in cylinder A. What is the density of the metal? The density of mercury is 13.6 g/cm3.arrow_forward
- The density of quartz mineral was determined by adding a weighed piece to a graduated cylinder containing 52.2 mL water. After the quartz was submerged, the water level was 67.1 mL. The quartz piece weighed 39.8 g. What was the density of the quartz?arrow_forwardConsider multiplying “26.2” by “16.43.” What would a mathematician say the answer is? What would a scientist say? Justify the scientist’s answer, not merely citing the rule, hut explaining it.arrow_forwardWhen elemental iron corrodes it combines with oxygen in the air to ultimately form red brown iron(III) oxide which we call rust. (a) If a shiny iron nail with an initial mass of 23.2 g is weighed after being coated in a layer of rust, would you expect the mass to have increased, decreased, or remained the same? Explain. (b) If the mass of the iron nail increases to 24.1 g, what mass of oxygen combined with the iron?arrow_forward
