An unknown compound has the following chemical formula: \[ \operatorname{Cr}(\mathrm{OH})_{\mathrm{x}} \] where \( x \) stands for a whole number. Measurements also show that a certain sample of the unknown compound contains 7.90 mol of oxygen and 2.63 mol of chromium. Write the complete chemical formula for the unknown compound.

Solve the equation and check the solution. \( -\frac{7}{4} x=-42 \)
