Density of gold is 19.3 g/cm^3 what is the mass of nugget that has a volume 1.47cm^3

28.372 grams is the mass of nugget.

Explanation:

Density is defined as mass of the substance present in unit volume of the substance.

Mass of gold nugget = m

Volume of gold nugget = V =

Density of the gold =

28.372 grams is the mass of nugget.

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%
