The radius of a tungsten atom is 137 pm. How many tungsten atoms would have to be laid side by side to span a distance of 1.29 mm? atoms The mass of a single niobium atom is 1.54x10-22 grams. How many niobium atoms would there be in 141 milligrams of niobium? atoms First she measured the mass of the metal to be 185.6 grams. Then she dropped the metal into a measuring cup and found that it displaced 17.5 mL of water. Calculate the density of the metal. Density = g/ml Use the table below to decide the identity of the metal. This metal is most likely Densities of Some Common Substances Substance Density (g/ml) Water 1.00 Aluminum 2.72 Chromium 7.25 Nickel 8.91 8.94 Copper Silver 10.50 Lead 11.34 13.60 Mercury Gold 19.28 Tungsten 19.38 Previous Platinum 21.46 Topics [References) Substance Density (g/mL) Water 1.00 Aluminum 2.72 Chromium 7.25 Nickel 8.91 8.94 Copper Silver 10.50 Lead 11.34 13.60 Mercury Gold 19.28 19.38 Tungsten Platinum 21.46 16.7 ml Pbx = 9 Pb Drag and drop your selection from the following list to complete the answer: 11.34 g Pb 11.34 ml Pb 1 ml Pb 1 g Pb
