You should get 5.05 x 10^23 moles.
Answer:
B
Explanation:
Generally, when you dilute something, your goal is to thin your concentration. Even if you added a solute, if your goal is dilution, it will make the concentration decrease.
The ionic compound will be soluble in water.
Ions are present in ionic compounds, which are held together by the attraction interactions between the ions with opposing charges. One of the most well-known ionic compounds is table salt or sodium chloride. Molecular compounds are made up of separate molecules that are connected by sharing electrons (covalent bonding).
High melting points are found in ionic substances. ionic compounds are brittle and rigid. When an ionic chemical is dissolved in water, it separates into ions. Ionic compound solutions and melting forms of these substances carry electricity, while solid materials do not.
A substance's heat of solution value is one of the criteria that determine whether or not it will dissolve. The Ionic compound will dissolve in water because a negative heat of the solution indicates that the reaction will be spontaneous.

<span>acceleration I think.</span>
A hiker climbs to the top of a mountain at rate of 0.5 m/hr. The speed of hiker is 1.3 x 10⁻⁴ m/s and the velocity of the hiker is 1.3 x 10⁻⁴ m/s west.
Speed is a scalar quantity. It is used to measure the distance traveled in a period of time. It is represented by -
s = d/Δt
where,
s = speed
d = distance
Δt = change in time
Velocity is a vector quantity. It is used to measure the change in position, that is, displacement over the change in time. It is represented by -
v = Δs / Δt
where,
v = velocity
Δs = change in position/displacement
Δt = change in time
The standard unit of velocity and speed both is m/s.
