To calculate the number of moles of CoCl3 in the solution, we need to divide the mass of CoCl3 by its molar mass.
Molar mass of CoCl3 = 129.84 g/mol
Number of moles of CoCl3 = 2.675 g / 129.84 g/mol = 0.0206 mol
Therefore, the solution contains 0.0206 mol of CoCl3.
Molar mass of CoCl3 = 129.84 g/mol
Number of moles of CoCl3 = 2.675 g / 129.84 g/mol = 0.0206 mol
Therefore, the solution contains 0.0206 mol of CoCl3.

To find the number of moles of CoCl3 in the solution, we need to divide the given mass by the molar mass of CoCl3.
Molar mass of CoCl3 = 58.933 g/mol + 35.453 g/mol x 3 = 165.87 g/mol
Number of moles of CoCl3 = 2.675 g / 165.87 g/mol = 0.0161 mol
Therefore, there are 0.0161 moles of CoCl3 in the solution.
Molar mass of CoCl3 = 58.933 g/mol + 35.453 g/mol x 3 = 165.87 g/mol
Number of moles of CoCl3 = 2.675 g / 165.87 g/mol = 0.0161 mol
Therefore, there are 0.0161 moles of CoCl3 in the solution.
