Amixture requires constant shaking to keep its constituents combined. it is best described as a homogenous mixture colloid suspension solution

The correct answer is a suspension.

A suspension is a mixture containing relatively large particles that settle fast

A homogenous mixture is a mixture where everything looks the same throughout and is all in the same phases

A colloid is a heterogenous mixture where the particles are small enough to stay suspended (usually talking about gaseous solutions)

And a solution is a homogenous mixture where the particles are too small to even reflect light

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%
