Subject : Chemistry

Question: You have a 100 gram sample of each of the following metals. Which sample has the largest volume?

(*The sample with the lowest density would have the greatest volume)

1) aluminum, d= 2.7 g/cm^3

2) gold, d = 19.3 g/cm^3

3) iron, d = 7.86 g/cm^3

4) magnesium, d = 1.74 g/cm^3

5) silver, d = 10.5 g/cm^3

Expert Verified Solution:

To determine which sample has the largest volume, we need to calculate the volume of each metal sample using the formula for density:

Density=MassVolume\text{Density} = \frac{\text{Mass}}{\text{Volume}}Rearranging the formula to solve for volume:

Volume=MassDensity\text{Volume} = \frac{\text{Mass}}{\text{Density}}Given that the mass of each sample is 100 grams, we can calculate the volume for each metal:

  1. Aluminum (d = 2.7 g/cm³):

Volume=100 g2.7 g/cm3≈37.04 cm3\text{Volume} = \frac{100 \, \text{g}}{2.7 \, \text{g/cm}^3} \approx 37.04 \, \text{cm}^3

  1. Gold (d = 19.3 g/cm³):

Volume=100 g19.3 g/cm3≈5.18 cm3\text{Volume} = \frac{100 \, \text{g}}{19.3 \, \text{g/cm}^3} \approx 5.18 \, \text{cm}^3

  1. Iron (d = 7.86 g/cm³):

Volume=100 g7.86 g/cm3≈12.73 cm3\text{Volume} = \frac{100 \, \text{g}}{7.86 \, \text{g/cm}^3} \approx 12.73 \, \text{cm}^3

  1. Magnesium (d = 1.74 g/cm³):

Volume=100 g1.74 g/cm3≈57.47 cm3\text{Volume} = \frac{100 \, \text{g}}{1.74 \, \text{g/cm}^3} \approx 57.47 \, \text{cm}^3

  1. Silver (d = 10.5 g/cm³):

Volume=100 g10.5 g/cm3≈9.52 cm3\text{Volume} = \frac{100 \, \text{g}}{10.5 \, \text{g/cm}^3} \approx 9.52 \, \text{cm}^3The metal with the largest volume is magnesium, with a volume of approximately 57.47 cm³. This is because magnesium has the lowest density (1.74 g/cm³) among the given metals.
