The density (d) of a substance is an intensive property that is defined as the ratio of its mass (m) to its volume (v).
density= mass/volume d=m/v
considering that mass and volume are both extensive properties, explain why their ratio, desity, is intensive.

Answer with explanation:

Extensive properties depend on the total matter while intensive properties do not, mass and volume are extensive properties because a bigger mass and a bigger volume are indicative of a more massive object, on the other hand, a more colorful or denser object is not an indication of a more massive object. Density, in particular, is a ratio so it will always be the same regardless of the size of the object, therefore, it is not directly related with the total amount of mass; to better understand this concept imagine you have a bag of sand and you add more sand to the bag, you are increasing the mass and the volume but because both increases the ration m/V do not.

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
