- 1.47 A student weighs 10 quarters and finds that their total mass is 56.63 grams. What should she report as the average mass of quarter based on her data?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 494 cm3 to mL, b 1.91 L to mL, c 874 cm3 to Larrow_forward
- a 90.8 mL to L and cm3, b 16.9 L to mL and cm3, c 65.4 cm 3 to mL and L.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_forwardA certain sample of the mineral galena (lead sulfide) weighs 12.4 g and has a volume of 1.64 cm3. What is the density of galena?arrow_forward
- 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_forwardWhat is the mass of a 43.8-mL sample of gasoline, which has a density of 0.70 g/cm3?arrow_forward1.48 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_forward
- A rectangular block has dimensions 2.9 cm 3.5 cm 10.0 cm. The mass of the block is 615.0 g. What are the volume and density of the block?arrow_forwardA solid metal sphere has a volume of 4.2 ft3. The mass of the sphere is 155 lb. Find the density of the metal sphere in grains per cubic centimeter.arrow_forwardHow many square meters will 4.0 L (about 1 gal) of paint cover if it is applied to a uniform thickness of 8.00 102 mm (volume = thickness area)?arrow_forward
