molar mass 10 g of Cu(OH)2
To calculate the molar mass of Cu(OH)2, you need to calculate the molar mass of each element present in the compound and then add them together.
Cu (Copper) has an atomic mass of approximately 63.55 g/mol.
O (Oxygen) has an atomic mass of approximately 16.00 g/mol.
H (Hydrogen) has an atomic mass of approximately 1.01 g/mol.
Cu(OH)2 contains one copper atom (Cu), two hydrogen atoms (H), and two oxygen atoms (O).
Molar mass of Cu(OH)2 = (molar mass of Cu) + 2*(molar mass of H) + 2*(molar mass of O)
= (63.55 g/mol) + 2*(1.01 g/mol) + 2*(16.00 g/mol)
= 63.55 g/mol + 2.02 g/mol + 32.00 g/mol
= 97.57 g/mol
Therefore, the molar mass of Cu(OH)2 is approximately 97.57 g/mol.
To calculate the molar mass of Cu(OH)2, you need to find the atomic masses of copper (Cu), oxygen (O), and hydrogen (H) from the periodic table and multiply them by the respective number of atoms in the chemical formula.
The atomic mass of copper (Cu) is 63.55 g/mol.
The atomic mass of oxygen (O) is 16.00 g/mol.
The atomic mass of hydrogen (H) is 1.01 g/mol.
In the compound Cu(OH)2, there is 1 atom of copper, 2 atoms of hydrogen, and 2 atoms of oxygen.
Now, let's calculate the molar mass:
Molar mass = (atomic mass of Cu × number of Cu atoms) + (atomic mass of O × number of O atoms) + (atomic mass of H × number of H atoms)
= (63.55 g/mol × 1) + (16.00 g/mol × 2) + (1.01 g/mol × 2)
= 63.55 g/mol + 32.00 g/mol + 2.02 g/mol
= 97.57 g/mol
So, the molar mass of Cu(OH)2 is 97.57 g/mol.
If you have 10 g of Cu(OH)2, you can calculate the number of moles by dividing the given mass by the molar mass:
Number of moles = Mass / Molar mass
= 10 g / 97.57 g/mol
= 0.1023 mol
I hope this helps! Let me know if you have any further questions.
To calculate the molar mass of Cu(OH)2, you need to find the atomic masses of all the elements present in the compound and multiply them by their respective subscripts.
The atomic masses of the elements are as follows:
- Copper (Cu): 63.55 g/mol
- Oxygen (O): 16.00 g/mol
- Hydrogen (H): 1.01 g/mol
The compound Cu(OH)2 contains one copper atom, two oxygen atoms, and two hydrogen atoms. So, now we can calculate the molar mass.
Molar mass of Cu(OH)2 = (atomic mass of Cu) + (atomic mass of O) + (atomic mass of H) + (atomic mass of H)
Molar mass of Cu(OH)2 = (63.55 g/mol) + (16.00 g/mol) + (1.01 g/mol) + (1.01 g/mol)
Molar mass of Cu(OH)2 = 82.53 g/mol
Therefore, the molar mass of Cu(OH)2 is 82.53 g/mol.
By using the atomic masses of each element and considering their respective subscripts, we can calculate the molar mass of any compound.
