What is the molarity of a solution formed when you add 200. Ml of water to 50. Ml of 5. 0 m hcl
Gnesinka [82]

The molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.

<h3>How to calculate molarity?</h3>

The molarity of a solution can be calculated using the following formula:

M1V1 = M2V2

Where;

  • M1 = molarity of a base
  • M2 = molarity of acid
  • V1 = volume of base
  • V2 = volume of acid

M1 × 200 = 50 × 5

200M1 = 250

M1 = 250/200

M1 = 1.25M

Therefore, the molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.

Using the diagram below, explain how the subsystems of the earth interact with each other?
solong [7]

Answer:

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). ... Interactions also occur among the spheres; for example, a change in the atmosphere can cause a change in the hydrosphere, and vice versa.
