Check the following problem for errors. if you find an error, identify it, tell why it is an error and correct the error solving the problem correctly. convert 0.45 g zinc hydroxide to moles. (hint: there are errors) 0.65 g znoh 82.41 mol = 3.22 x 10 25 mol 6.02x1023 g

The question says only to convert the Zn(OH)₂ into moles. But the given answer has many errors such as formula, mass and moles.

The corrected answer is as follows.

Moles (mol) = mass (g) / molar mass (g/mol)

Mass of Zn(OH)₂ = 0.45 g
Molar mass of Zn(OH)₂ = 99.424 g/mol
Hence, moles of Zn(OH)₂ = 0.45 g / 99.424 g/mol
                                         = 4.526 x 10⁻³ mol

Where is the following?
