- The 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_forwardWrite the following measurements, without scientific notation, using the appropriate SI prefix. a 4.851 106 g b 3.16 102 m c 2.591 109 s d 8.93 1012 garrow_forwardWhat is the difference between reporting the quantity nine inches as 9 inches and 9.00 inches?arrow_forward
- Vanadium metal is added to steel to impart strength. The density of vanadium is 5.96 g/cm3. Express this in SI units (kg/m3).arrow_forwardZinc ore (zinc sulfide) is treated with sulfuric acid, leaving a solution with some undissolved bits of material and releasing hydrogen sulfide gas. If 10.8 g of zinc ore is treated with 50.0 mL of sulfuric arid (density 1.153 g/mL), 65.1 g of solution and undissolved material remains. In addition, hydrogen sulfide (density 1.393 g/L) is evolved. What is the volume (in liters) of this gas?arrow_forward1.90 A calibrated flask was filled to the 25.00-mL mark with ethyl alcohol and was found to have a mass of 19.7325 g. In a second experiment, 25.0920 g of metal beads were put into the container and the flask was again filled to the 25.00-mL mark. The total mass of the metal plus the alcohol was 43 .0725 g. Describe how to determine the density of the metal sample.arrow_forward
- 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 weather balloon filled with helium has a diameter of 3.50 ft. What is the mass in grams of the helium in the balloon at 21C and normal pressure? The density of helium under these conditions is 0.166 g/L.arrow_forwardWrite the following measurements, without scientific notation, using the appropriate SI prefix. a 5.89 1012 s b 0.2010 m c 2.560 109 g d 6.05 105 marrow_forward
- 1.65 An industrial engineer is designing a process to manufacture bullets. The mass of each bullet must be within 0.2 5% of 150 grains. What range of bullet masses, in mg, will meet this tolerance? 1 grain = 64.79891 mg.arrow_forwardList the more common types of measurements made in chemical laboratories.arrow_forwardGold leaf, which is used for many decorative purposes, is made by hammering pure gold into very thin sheets. Assuming that a sheet of gold leaf is 1.27 105 cm thick, how many square feet of gold leaf could be obtained from 28.35 g gold? The density of gold is 19.3 g/cm3.arrow_forward
