Just multiply the molar mass of gold with the number of moles of gold to cancel out the moles in the denominator:
0.147 mol * 196.97 g/mol = 28.95459 grams
0.147 mol * 196.97 g/mol = 28.95459 grams

0.147 mol * 196.97 g/mol = 28.95459 grams
NOTE: Just as a side note, you have 3 places in 0.147 so you can't have more than 3 in the answer so I would round 28.95459 to 29.0
