A block of lead has dimensions of 4.5 cm by 5.2 cm by 6.0 cm. Dividing 78.19 g by 6.8 mL yields a density for the rock equal to 11 g/mL. So it is expected that the smallest piece of matter, like an atom of Lead has it too.
27kwh/L beats the pants off everything for maximum energy in … Again I entered density of metals in Google and I was linked to many lists that gave the same figures for the density of lead. Note: Learn more about the density here.
PROBLEMS : (show your work) After doing this lab and completing the chart, you should be able to do these problems: High-silicon bronze and low-silicon bronze have similar densities, but the density of low-silicon bronze is a little higher at 8.75 grams per cubic centimeter. Calculate the radius of a niobium atom. Subtracting the initial volume of water from the final volume of water (56.8 - 50.0) gives the volume of the rock, 6.8 mL.
However, there are interesting facts about Lead that most don't know about. Give two reasons why there is a difference between the given density and the your calculated density (concentrate on the equipment you had to use) .
The volume of 20.0 grams of lead is 1.77 mL. ρ = m/V
Definitions and convertion calculators. The block weighs 1587 g. From this information, calculate the density of lead.
Semicore Equipment, Inc. is a leading worldwide supplier of PVD Coating Equipment for the electronics, medical, automotive, optical, solar energy, military and related high technology industries.. \$\begingroup\$ As I understand it, the Vanadium-Boride-Air battery has a theoretical energy density on the order of 27kwh/liter, I forget what that worked out to in kwh/kg, but petrol's only ~10kwh/L. For instance I looked up LEAD in Wikipedia, and found that the density is quoted as: 11.34 g/cm³. The density of lead (ρ) is 11.3 g/mL. Related Topics . The density of bronze made with copper and manganese is 8.36 grams per cubic centimeter. Now the density formula from before can be utilized to find the density of the object. In general, metals are more dense than non-metals. Density of lead = g mL mL g volume mass 11.3 / 1.77 20.0 = = The volume of 20.0 g of aluminum is 7.41 mL.
(1) For example, at 25°C the density of metallic lead is 11.4 g mL-1 while the density of non-metallic sulfur is only 2.0 g mL-1. Everything has mass and volume, and therefore density.
The mass of lead contained in each mL is its density. Answer: 915 g. Explanation: The volume of lead (V) is equal to the difference between the final level of water and the initial level of water.. V = 287 mL - 206 mL = 81.0 mL. Here is my question Niobium has a density of $8.57 \\pu{g/cm^3}$ and crystallizes with the body-centered cubic unit cell. Material Properties - Material properties for gases, fluids and solids - densities, specific heats, viscosities and more ; Density - Density of different solid materials, liquids and gases. This bronze has a density of 8.17 grams per cubic centimeter. I cannot see any reason why a so-called theoretical density of lead should be any different from these values. Here is my solution This means that the mass of 1 mL of lead would be 11.4 g while the mass of 1 mL of sulfur would be only 2.0 g. Related Documents . But what is the density of an atom of Pb? We can find the mass of lead (m), in grams, using the following expression.
