- The label on a bale of mulch indicates a volume of 1.45 ft3. The label also states that the mulch in the bale will cover an area of a garden 6 ft 6 ft to a depth of 1 in. Account for the discrepancy in the given volumes.arrow_forwardA sample of a bright blue mineral was weighed in air, then weighed again while suspended in water. An object is buoyed up by the mass of the fluid displaced by the object. In air, the mineral weighed 7.35 g; in water, it weighed 5.40 g. The densities of air and water are 1.205 g/L and 0.9982 g/cm3, respectively. What is the density of the mineral?arrow_forwardAlthough the preferred SI unit of area is the square meter, land is often measured in the metric system in hectares (ha). One hectare is equal to 10,000 m2. In the English system, land is often measured in acres (1 acre = 160 rod2). Use the exact conversions and those given in Exercise 47 to calculate the following. a. 1 ha = __________ km2 b. The area of a 5.5-acre plot of land in hectares, square meters, and square kilometers c. A lot with dimensions 120 ft by 75 ft is to be sold for 6500. What is the price per acre? What is the price per hectare?arrow_forward
- A solution is prepared by dissolving table salt, sodium chloride, in water at room temperature. a Assuming there is no significant change in the volume of water during the preparation of the solution, how would the density of the solution compare to that of pure water? b If you were to boil the solution for several minutes and then allow it to cool to room temperature, how would the density of the solution compare to the density in part a? c If you took the solution prepared in part a and added more water, how would this affect the density of the solution?arrow_forwardThe density of a solution of sulfuric acid is 1.285 g/cm3, and it is 38.08% acid by mass. Calculate the volume of the acid solution (in mL) you need to supply 125 g of sulfuric acid.arrow_forwardIf mercury (density = 13.6 g/cm3) at a height of 895 mm Hg in a mercury barometer is replaced with water (density = 1.00 g/cm3), under the same conditions the height of water will be. (The unit of your answer should be in meter with five significant figures)arrow_forward
- A parsec is an astronomical unit of distance where 1 parsec = 3.26 light years (1 light year equals the distance traveled by light in one year). If the speed of light is 186,000 mi/s, what is the distance in meters of an object that travels 6.1 parsecs?arrow_forwardNear room temperature, liquid benzene (C,H,) has a density of 0.8765 g cm3. Suppose that 0.2124 L of benzene is measured into a container. Calculate (a) the mass and (b) the chemical amount of benzene in the container. Mass (g Density = Volume (cm') 55arrow_forwardA parsec is an astronomical unit of distance. 1 parsec = 3.26 light years (where 1 light year is the distance traveled by light in one year). Lightspeed = 186,000 miles per second. An object travels 9.6 parsecs. Calculate this distance in cm.arrow_forward
- In an attempt to determine the velocity of a person on a bicycle, an observer uses a stopwatch and fi nds the length of time it takes to cover 25 “squares” on a sidewalk. The bicycle takes 4.82 seconds to travel this far. A measurement of one of the squares shows that it is 1.13 m long. What velocity, in m/s, should the observer report?arrow_forwardthe unit of land measure in the english system is the acre, while that in the metric system is the hectare. An acre is 4.356 x 10^4 ft^4. A hectare is ten thousand square meters. The town of willington in connecticut requires a minimum area of 2.0 acres of land for a single-family dwelling. How many hectares are required?arrow_forwardIn water conversation, chemistry spread a thin certain inert materials over the surface of water cut down on the rate of evaporation of water in reservoirs. This technique was pioneered by Benjamin Franklin three centuries ago. Franklin found that 0.10mL of oil could spread the surface of water of about 42.9m2 in area. Assuming that oil forms a monolayer ( that is, a layer that is only one molecules are roughly cubic. (1mm=1*10^-9m)arrow_forward
