It all depends what the substance is.
If it's 28 grams of air, the volume is large.
If it's 28 grams of rock or lead, the volume is much smaller.

To determine the volume of a substance given its mass, you need to know its density. Without the density information, it is not possible to accurately calculate the volume. Density is the ratio of mass to volume.
Density is calculated by dividing the mass (in grams) of a substance by its volume (in milliliters or cubic centimeters). The formula for density is: Density = Mass / Volume. By measuring the mass of a sample in grams and the volume in milliliters, you can easily calculate the density of the substance.
The volume of the substance can be found by dividing the mass by the density. In this case, the volume is 554 grams / 3.1 grams per cubic centimeter, which equals 178.71 cubic centimeters.
denisity = mass/volume = 67.7 grams/12.8 mL = 5.29 g/mL
The mass is 146,835 grams.
The mass of the platinum disk can be calculated using the formula: mass = volume * density. Plugging in the values gives mass = 113 * 21.4 = 2428.2 grams. Therefore, the mass of the pure platinum disk is 2428.2 grams.
