A. 1.79kg

Explanation:

The value of the mass of a particular substance could be obtained if there is adequate information about the volume of that particular substance and the density of that substance.

Mathematically expressed, the mass of a substance is the product of the density and the volume.

In this particular question, the density is 0.01932kg/cm3 while the volume is 92.5cm3

The mass is thus = 92.5 * 0.01932 = 1.7871kg which is approximately 1.79kg
