- two strips of metal each weighing 100g are placed into a cylinder containing water. The volume of water displaced is 8.8 ml in one case and 37.0ml in the other case. identify the two metal strips. AU Fe Al Pb Ag 19.3 7.9 2.7 11.3 10.5 * For this question do i have to do any calculations? Or just state that Fe is Iron, Ag is silver etc.? Which weighs the most, 10cm3 of iron or 5.0cm3 of silver?arrow_forwardAn engineer is working with archaeologists to create a realistic Roman village in a museum. The plan for a balancein a marketplace calls for 100 granite stones, each weighing 10 denarium. (The denarium was a Roman unit of mass:1 denarium = 3.396 g.) The manufacturing process for making the stones will remove 20% of the material. If the graniteto be used has a density of 2.75 g/cm3, what is the minimumvolume of granite that the engineer should order?arrow_forwardIn a clean and dry crucible with cover weighing 24.342 g some of the unknown hydrate (CuSO4.nH2O) was placed in the crucible to reach a mass of 27.557 g. The crucible was heated several times until it reached a final constant mass of 26.403 g. Use these measurements to complete your data sheet and show complete calculation for the missing values.arrow_forward
- Swimming pool water is often made safe for swimming by treating with chlorine in the form of sodium hypocholrite (NaOCI) solution. If a swimming pool contains 5.62×10^5L of water, what volume of 5.00% NaOCI (by mass) solution is required to produce a sodium hypoclorite concentrarion of 3.00×10^-7 mol /L? (assuume the density of water and the NaOCI solution is 1.00g/ml). Do not give handwriting solution.arrow_forwarda sample of unknown mixture has a total mass of 134g, a total volume of 113 cm3, and consists only of an unknown A (density=1.4 g/cm3) and B (density=1.122g/cm3). what is the volume of component B in this mixture? Assume that the volumes are additive.arrow_forwardEvery year in the United States, about 12 million tons of magnesium metal are used to manufacture the sacrificial anodes that prevent the corrosion of iron structures. The required magnesium can be obtained by processing seawater. Seawater has a density of 1.025 g/mL and one kilogram of seawater contains 1.4 g of magnesium. What volume of seawater, in cubic kilometers, would need to be processed to provide theU.S. with a one-year supply of magnesium? 1 ton = 2000 lbs. ...arrow_forward
- When left in an open beaker for a period of time, the volume of 275 mL of 0.105 M NaCl is found to decrease to 237 mL because of the evaporation of water. What is the new concentration in M of the solution?arrow_forward(a) A solution of 20.91 % by weight H₂SO4, has a specific gravity of 1.150. What is the normality of this solution? (b) Water is added to dilute this solution to a solution of 3.03% by weight H2SO4 (SG=1.020). What is the new normality of the resulting solution and how were they mixed? (Assume 100 mL of the original solution was used.)arrow_forwardA solution of 20.91 % by weight H2SO4 has a specific gravity of 1.150. What is the normality ofthis solution? Water is added to dilute this solution to a solution of 3.03% by weight H2SO4(SG= 1.020). What is the new normality of the resulting solution and how were they mixed?(Assume 100 mL of the original solution was used.)arrow_forward
- The Greek mathematician Archimedes is credited with discovering how to verify the amount of pure gold in an irregularly shaped object (e.g., a crown) by placing it in water. How much water should be displaced by a pure gold object having a mass of 0.9000 kg?arrow_forwardA cylindrical bar was found at the bottom of a storage tank of unknown composition. The material had a diameter of 8 mm, a length of 62 cm and a mass of 0.018 kg. What is the density of this material in g/mL? The volume of a cylinder is given by V = πr^2h.arrow_forwardA pycnometer is a glass flask with a tight fitting glass stopper that can be used to determine the density of an insoluble solid by measuring the volume of water ejected out of the pycnometer when sample of the solid is placed in it. Determine the density in g/cm³ of an unknown metal alloy sample from the following measurements. Assume the density of water is 1.000 g/cm³.Mass of clean pycnometer = 25.151 gMass of clean pycnometer plus water = 42.481 gMass of clean pycnometer plus metal sample = 39.305 gMass of clean pycnometer plus metal plus water = 54.265 g (after ejected water is dried from the outside surface)arrow_forward
