[Given] 14.7 mol Au

[Solve] g Au

Step 2: Identify Conversion

[PT] Molar Mass of Au - 196.97 g/mol

Step 3: Convert

[DA] Set up:                                                                                                     [DA] Multiply [Cancel out units]:                                                                    

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

2895.46 g Au ≈ 2900 g Au

The answer is b metal denting
