Calculate the mass of copper in grams (density = 8.96 g/cm3) with the same volume as...
A cube of copper metal has a density of 8.96 g/cm3. The cube has a mass of 29.54 g. The atomic radius of a copper atom is 1.28 angstroms. How many atoms is the cube of copper metal?
25. The density of copper is about 8.96 g/mL. This means that a certain mass of copper will: a) Occupy the same volume as the same mass of water b Occupy a volume 8.96 times larger than the volume occupied by the same mass of water c) Occupy a volume that is 8.96 times smaller than the volume occupied by the same mass of water d) Always occupy a volume of 8.96 ml 26. 164.0 g of a substance occupy...
The mass unit associated with density is usually grams. If the volume (in mL or cm3) is multiplied by the density (g/mL or g/cm3) the volume units will cancel out, leaving only the mass units. Keep in mind that the volume and density must use the same volume unit for the cancellation. If a large marshmallow has a volume of 2.00 in3 and density of 0.242 g/cm3, how much would it weigh in grams? 1 in3=16.39 cm3
The density of pure copper is 8.96 g/cm3. Before mid-1982 Lincoln pennies were made from pure copper and weighed 3.11 g each. What is the volume of 81.2 pre-1982 Lincoln pennies?
If copper has a density of 8.96 g/cm^3, what is the volume of 6000 g of copper?
Metal Cu Ag Mass (g) 15 15 Specific heat (J/g·°C) 0.385 0.240 Density (g/cm3) 8.96 1.049 Both of these metals are heated with the same amount of heat energy for 10 minutes. Which sample will reach the higher temperature and why? Copper because it is less dense Silver becaue it is more dense Silver because it has a lower specific heat Copper because it has a higher specific heat
The density of gold is 19.3 g/cm3. What volume (cm3) would be occupied by a piece of gold with a mass of 103.5 g?
Red gold is a gold‑copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 8.35 g and has a volume of 0.581 cm3. Gold has a density of 19.3 g/cm3 and copper has a density of 8.96 g/cm3. Calculate the percentage by mass of each metal in the jewelry. Assume the total volume of the jewelry is the sum of the volumes of the two metals it contains. gold: % : copper: % : Pure...
Red gold is a gold‑copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 8.80 g and has a volume of 0.594 cm3. Gold has a density of 19.3 g/cm3 and copper has a density of 8.96 g/cm3 . Calculate the percentage by mass of each metal in the jewelry. Assume the total volume of the jewelry is the sum of the volumes of the two metals it contains. gold: % copper: % Pure gold...
The density of copper is 8.96 g/cm^3. you need 533 g of copper sheeting for a project, and you know that manufacturing will remove 25% of the material. what volume of copper should you order ?
