Find the mass of 1 cm3 of copper.
density= mass / volume
mass= density * volume (density is about 8.96 g cm-3)
mass= 8.96 g cm-3 * 1 cm3 = 8.96 g
no. of moles = mass / Molar mass =8.96 g / 63.5 g mol-1 = 0.14 mol
no. of copper atoms in 1 cm3 of copper= 0.14 mol * 6.022 *1023 =8.4 * 1022 atoms
Here is the process for finding the answer. Weigh one cubic centimeter of copper on a scale that reports the weight in grams. Take that weight, in grams), and multiply it by 63.546 (which is the atomic weight of copper) to get how many gram atomic weights of copper is in one cubic centimeter of copper. Take that number and multiply it times Avagadros Number which is the number of atoms in one gram atomic weight of any element. The resulting number is how many atoms are in one cubic centimeter of copper. Avagadros Number is shown below:
6.0221415 × 1023
4.02*10625
1 mL of water equals 1cm^3 of volume, so 1.72 ml= 1.72 cm
32km (20 miles)40/0.1= 400Earth's Diameter = 12756km12756/400= 31.9km
The plates move at rates 1cm-12cm per Year.
The total space etween stationary boundry is 1cm .Ethylen glycol is laced on the left side and propylene glycol is placed on the right . When the infinite plate that seartae the liquids is pulled upward,it finds an equilirium position. Determine the lateral location of the plate if it has a thickness of 1mm.
1mm of rain is actually water volume of 1lt per 1m2 of surface, 1mm=1lt/1m2 explanation: Simply convert 1lt to 1000 ml. Since 1ml=1cm3 and 1cm=0.01m=10-2m then 1cm3 = 10-6m3 this means that 1lt=1000ml=1000cm3 = 1000 x 10-6m3= 10-3m3 So 1lt/1m2 from the above is 10-3m3/1m2= 10-3m = 1mm. I hope that it is not complicated.
this means that copper is 2.7g/cm3

We need to know the diameter of the wire to calculate the volume and the mass. Number of atoms is: 2,58.1023.r2, where r is the radius of the wire.

There would be 1,452 1cm cubes that fit in a 12cmx12cmx11cm cube. This is determined by multiplying the dimensions of the larger cube together (12x12x11) and dividing by the volume of the smaller cubes, which is 1cm^3.
A centicube is a cube measuring 1cm x 1cm x 1cm or 1cm3
A cube has 6 sides, therefore a 1cm cube has a total surface area of 6 square centimeters.
Volume of a cube = (side × side × side) cubic units. V=1cm x 1cm x 1cm V = 1cm^3
A cube cannot have sides with different lengths.
6CM3
They are the same.
