If the density of silver is 10.5 gm/mL, what is the mass of 1 cubic foot?
The mass density of silver at room temperature is 10.5 x 103 kg/m3 and its atomic mass is 108g/mol. If we assume there is one free electron per silver atom, what is the free-electron desity for silver, in electrons/m3? How does this compare to the free electron density of Copper?
The density of a metal is 4.0 g/ml. What is the mass of a cubic block of a metal measuring 1.5 m on each side ?
The wet density at the maximum density is 120 pounds per cubic foot and optimum water content is 9%. The specific gravity is 2.81. The soil is to be compacted to a minimum of 90% of the maximum density. What dry density must the soil be compacted to in the field?
Sig. Figs Question #1 A) A graduated cylinder contains 18.0 mL of water. What is the new water level after 35.6 g of silver metal with a density of 10.5 g/mL is submerged in the water? B) How many cubic centimeters (cm3) of olive oil have the same mass as 1.00 L of gasoline? density: olive oil = 0.92 g/mL, gasoline = 0.66 g/mL c) The area of a triangle is 67.4 in2. Convert this area to cm2. (1 inch...
1) The density of pure silver is 10.5g/mL. If 4287mg of pure silver pellets are added to a graduated cylinder containing 26.4mL of water, to what level will the water in the cylinder rise? (5 points)

An 18-karat gold necklace is 75% gold by mass, 16% silver, and 9.0% copper.If 18-karat gold has a density of 15.5 , what is the volume in cubic centimeters?
The residential rate for natural gas is about $15 per thousand cubic foot. Burning one cubic foot of natural gas releases about 1080 kJ of heat. How much would it cost, in US$, to heat the water in a 25,000 gallon swimming pool from 52*F to 78*F, assuming all of the heat from the burning natural gas went towards warming the water? (1 gal = 3.785L ; specific heat of water = 4.184 J/g*C ; water density = 1.00g/mL).
A mechanical pencil has the density of3 grams per cubic centimeter.The volume of the pencil is 15.8 cubic centimeters. what is the mass of the pencil?
Sterling silver is a solid solution of silver and copper. If a piece of a sterling silver necklace has a mass of 160.0 g and a volume of 15.42 mL, calculate the mass percent of copper in the piece of necklace. Assume that the volume of silver present plus the volume of copper present equals the total volume. (Density of Cu = 8.96 g/cm^3: density of Ag = 10.5 g/cm.) mass percent of copper = mass of copper/total mass times...
