A scientist would like to make 450.0 mL of a 0.0200 M HCl by diluting a 7.00 M HCl solution. What volume of the 7.00 M HCl solution should the scientist use?

The volume : V₁ = 1.29 ml

Given

V₂=450 ml

M₂=0.02

M₁=7.0

Required

V₂

Solution

Dilution is the process of adding solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

n₁=n₂

Dilution formula :

M₁V₁=M₂V₂

Input the value

V₁= (M₂V₂)/M₁

V₁ = (0.02 x 450)/7

V₁ = 1.29 ml

most sediment washes or falls into the river as a result of mass movement and runoff. other sediment eroded from the bottom or sides of the river.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
