A 6.0 M HCI solution is diluted to make 500 mL of a 2.5 M HCI solution. What volume of the 6.0 M HCI solution is required to make this solution?

V₁   = 208.3 mL

Explanation:

Given data:

Initial molarity of HCl  = 6.0 M

Final volume = 500 mL

Final molarity = 2.5 M

Volume of initial solution required = ?

Solution:

Formula:

M₁V₁   =  M₂V₂

Now we will put the values in formula.

6.0 M × V₁   = 2.5 M ×500 mL

6.0 M × V₁   = 1250 M.mL

V₁   = 1250 M.mL / 6.0 M

V₁   = 208.3 mL

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
