calculate the percentage copper in copper 2 nitrate
Cu(NO3)2.
%Cu = [(mass Cu/mass Cu(NO3)2]*100 = ?
Note:Use molar masses for mass.
To calculate the percentage of copper in copper(II) nitrate, you need to consider the molar mass of copper(II) nitrate and the molar mass of copper. Here's how you can calculate it step by step:
1. Determine the formula of copper(II) nitrate.
Copper has two possible charges: +1 and +2. Since the compound is copper(II) nitrate, the copper ion carries a charge of +2. The formula for copper(II) nitrate is Cu(NO3)2.
2. Calculate the molar mass of copper(II) nitrate.
The molar mass of copper(II) nitrate can be calculated by adding up the atomic masses of all the atoms in the formula. The atomic mass of each atom can be found on the periodic table:
- Copper (Cu): 63.55 g/mol
- Nitrogen (N): 14.01 g/mol (There are 2 nitrogen atoms in the formula)
- Oxygen (O): 16.00 g/mol (There are 6 oxygen atoms in the formula)
Molar mass of copper(II) nitrate (Cu(NO3)2) = (1 × Copper) + (2 × Nitrogen) + (6 × Oxygen)
3. Calculate the molar mass of copper.
The molar mass of copper is 63.55 g/mol.
4. Calculate the percentage of copper in copper(II) nitrate.
The percentage of copper can be calculated using the following formula:
Percentage of copper = (Molar mass of copper / Molar mass of copper(II) nitrate) × 100
Substitute the molar mass values into the formula and calculate the percentage.
Note: The percentage you obtain represents the mass proportion of copper in the compound.
