The combination of the of two or more elements is known as a compound.
A homogenous mixture has a uniform composition all throughout. They are
similar in terms of the amount of composition present in a solution. For
example, oxygen is diatomic, O2. So oxygen is a compound because it has 2
elements combined in it. It is also a homogenous mixture if there are a lot of
O2 gases present in let’s say tank. They only differ in the place where they
are present. A compound is a representation of one molecule whereas a
homogenous mixture is present in a a solution.

Answer:
4.87 g
Explanation:
The formula between the number of moles, mass and Mr can be used to find the mass of barium.
<em>Number of moles = mass ÷ Mr</em>
So, mass = number of moles × Mr
Mr of Ba = 137.3
∴ Mass = (3.55 × 10⁻²) × 137.3 = 4.87 g
