Three samples of the same metal are weighed and their masses are found to be 42.02g,44.63g, and 44.16g. The corresponding volumes are 4.55mL,5.11mL, and 4.84mL, respectively. Determine the density, d, of the metal and calculate the standard deviation of the density. d= g/cm3 g/cm3 The densities of several metals are given in the table. Which of the metals could the sample be? gold cobalt aluminum copper iron
