The weight of 1 cubic meter of copper is approximately 8,960 kilograms.
One cubic foot of common red brick weigh 120 pounds. For fire clay bricks, the weight is 150 pounds per cubic foot.
The weight of 1 cu. ft. of aluminum is approximately 169 pounds. It is also equivalent to 76,500 grams or 76.5 kilograms. The chemical symbol for aluminum is Al.
1 cu ft = 0.037037 cu yeard
Soapstone weighs 180 lbs per cubic foot. As a shortcut, you can take the measurements in inches (length x width x height) and divide by 9.6. For example, if a large piece of soapstone was 18" x 15" x 20", it would weigh 18 x 15 x 20 (=5400) divided by 9.6 = 562.5 lbs.
A 2.18 moles of Cu has a weight of 138.53 g. This is obtained by multiplying the 2.18 by the weight of 1 mole of Cu.
The balanced chemical equation for the reaction between copper (Cu) and nitric acid (HNO3) is Cu + 4HNO3 -> Cu(NO3)2 + 2NO2 + 2H2O. From the equation, it can be seen that 1 mol of Cu reacts with 4 mol of HNO3. Therefore, to react with 2.0 mol of HNO3, 0.5 mol of Cu is needed. The molar mass of Cu is approximately 63.5 g/mol, so 0.5 mol of Cu would be equivalent to 31.75 grams.

The molar mass of copper is its atomic weight on the periodic table in g/mol, and is 63.5g/mol We know that one mole of copper contains 6.022×10^23 atoms of copper . First convert given mass to moles, and moles to atoms. = 61.0 g Cu × (1 mol Cu / 63.5 g per mol) ×6.022 × 10 ^23 atom cu / 1 mol Cu) = 5.78× 10^23. atoms. 61 g Cu 5.7 ×10^23 atoms of Cu.

To calculate the number of Cu atoms in 85 mol, you need to use Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. So, for 85 mol of Cu, the number of Cu atoms would be 85 mol x 6.022 x 10^23 atoms/mol = 5.12 x 10^25 Cu atoms.
The molar mass of Cu is 63.55 g/mol and of O is 16 g/mol. The moles of Cu used is 127g / 63.55 g/mol = 2 mol, and the moles of O used is 32g / 16 g/mol = 2 mol. Since the mole ratio of Cu to O in CuO is 1:1, then 2 mol of Cu will react with 2 mol of O to form 2 mol of CuO. The mass of 2 mol of CuO is 159.6g.
The mole in chemistry is also called the chemist's dozen and is defined as the amount of material containing 6.0221421 X10^23 particles(This number is called Avogadro's number) The value of mole is the number of particles in excactly 12 grams of c-12, so, if you have 12grams of c-12 , you will have 6.022x10^23 carbon atoms ,which is also a mol of C. For any other element a mol of that element is the Atomic Mass expressed as grams. 0.0265 g C find mol of C plan gC -> mol C 1 mol / 12.01 g C ( relationship; 1 mol C = 12.01 g C ) 0.0265 g C x 1 mol C / 12.01 g C = 2.21 x 10 ^-3 mol C to find atoms change to mol then times 6.022X10^23 3.10g Cu find Cu atoms plan g -> mol cu -> atoms Cu (3.10 g cu )x (1 mol Cu /63.55 g Cu ) ( 6.022 x 10^23 / 1 mol cu = 2.94 x 10^22 Cu atoms
