If you make a solution by adding 5.0 moles of sodium hydroxide to 25.0 moles of water, what is the mole fraction of sodium hydroxide in this solution?

Explanation:

The mole fraction (χ) is  the number of moles of a component divided by the total number of moles in a mixture.  

Let water = Component 1 and NaOH = component 2.

1. Calculate the total moles.

n₁ = 25.0 mol

n₂ = 5.0 mol

2. Calculate the mole fraction of NaOH

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
