It is found to displace 19.3 mL of water ( which means it has a volume of 19.3 mL) and has a mass of 371 grams. Could the nugget be made of gold? gold =19.3 g/cm3 d=M/v 371/19.3=19.2222 g/cm3 No Acetone (nail polish remover) has a density of .7857 g/cm3 a. What is the mass, in g. of 28.56 mL of acetone? b. What is the volume, in mL, of 6.54g of acetone? d=m/v.7857= m/28.56 a. m=22.54 .7857=6.54g/V Acetone (nail polish remover) has a density of .7857 g/cm3 AuthorCheetah13 ID303791 Card SetEXAM 1 DescriptionChemistry chapter one for miller Updated2015-06-09T10:31:23Z Show Answers
