An automobile company displays a die-cast model of its first car, made from 9.70 kg of iron. To celebrate its hundredth year in business, a worker will recast the model in solid gold from the original dies. What mass of gold is needed to make the new model? (The density o iron is 7.86 x 103 kg/m3, and that of gold is 19.30 x 103 kg/m3.) kg
