1. Gold (Au) has been used to make ornamental objects and jewelry for thousands of years. Gold nuggets found in a stream are very easy to work and were probably one of the first metals used by humans. (1 mol of Gold (Au) = 196.97g). Calculate the: %3D LMD A. Number of moles in a 95.0 g sample of a gold nugget. B. Number of atoms in a 95.0 g sample of a gold nugget.

Question
1. Gold (Au) has been used to make ornamental objects and jewelry for thousands of years. Gold nuggets found in a stream are very easy to work and were probably one of the first metals used by humans. (1 mol of Gold (Au) = 196.97g). Calculate the: 1 MD A. Number of moles in a 95.0 g sample of a gold nugget, B. Number of atoms in a 95.0 g sample of a gold nugget. 2. During exercise, lactic acid (C3H6O3) forms in the muscles causing muscle cramp. If 5.0 g of lactic acid (C3H6O3) concentrate in your leg muscles, how many molecules of lactic acid is causing you pain? (C = 0= 16.0 g/mol) 12.0g/mol, H = 1.008 g/mol, TE CALABE A
