i What is the volume of an object that has a mass of los grams and a dansity of 21

Density is defined as mass divided by volume (Density = Mass/Volume). We can rearrange this formula to solve for volume: Volume = Mass/Density.<br /><br />In this case, the mass is 105 grams and the density is 2 g/cm³ (I assume you meant 2, and the units are likely grams per cubic centimeter). Therefore:<br /><br />Volume = 105 g / 2 g/cm³ = 52.5 cm³<br /><br />So, the volume of the object is $\boxed{52.5 cm³}$.<br />
