Answer: A) 0.20 L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,

where,
= molarity of stock
solution = 10.0 M
= volume of stock
solution = ?
= molarity of dilute
solution = 0.50 M
= volume of dilute
solution = 4.0 L


Therefore, the volume of 10.0 M
solution needed to prepare 4.0 L of 0.50 M
is 0.20 L
Answer:
put a filter to see if there is any stagering solution
Explanation:
Explanation:
A) particles are close together in random positions with about equal kinetic energy and intermolecular forces.
These points are about liquid state.
B) particles are close together in fixed positions with low kinetic energy
These points satisfy the qualities of Solid state
C)particles are far apart with greater kinetic energy and low intermolecular forces.
The above qualities are for Gaseous state of matter
A) Liquid
B)Solid
C)Gas
Answer:
Nitrogen and Oxygen make up 99% of the Earths atmosphere. Then Argon makes up the rest of the atmosphere.
Answer:
2.48626 x 10^24
Explanation:
We multiple 4.13 by avogadro's number to get that.
