Answer:
The design of experiments (DOE, DOX, or experimental design) is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation. The term is generally associated with experiments in which the design introduces conditions that directly affect the variation, but may also refer to the design of quasi-experiments, in which natural conditions that influence the variation are selected for observation.
Explanation:
The volume occupied by the given mol of helium gas at the given temperature and pressure is 91.6L.
The Ideal gas Law, also called the overall fuel equation, is the equation of kingdom of a hypothetical ideal gas. It is a superb approximation of the conduct of many gases below many situations, even though it has several limitations.
The precise gas regulation states that PV = NRT, wherein P is absolutely the pressure of a gasoline,volume V is the quantity it occupies, N is the quantity of atoms and molecules inside the fuel, and T is its absolute temperature.
Given;
Amount of helium n = 2.59 mole
Pressure p = 0.826 atm
Temperature T = 356 K
The volume of Helium = ?
PV = nRT
V = nRT/P
V = 2.59 mole * 0.826 atm * 356K/0.826
V = 75.6626/0.826
V = 91.6 L

Hello there!
First, we need to know what compounds are. Compounds "are pure substances that are made up of two or more elements that are chemically combined in fixed mass ratios."
Now we need to understand what chemical formulas are.
The compounds have a chemical formula which tell us that
a) the elements that are present in the compound
b) the ratio of these elements in the compound
What are some chemical formulas for compounds?
Well, we start with water. The chemical formula for water is H2O
When we go back to the definition of compounds, it says it is when
a pure substance that are made up two or more elements. So, whatever is a pure substance and it's made up of two elements. These elements are Hydrogen and Oxygen. And keep an mind that water is made up with metal plus non-metal.

Here are one more chemical formulas for compounds
Sodium Chloride = NaCI

I believe the conversion for mL to cm^3 is 1:1 so just change 7.5mL to 7.5cm^3 and then divide 64.5 by it to get 8.6g/cm^3
