how many milliliters of .400M hydrogen Monobromide solution can be made from 50mL of 8M hydrogen monobromide solution?
Use the dilution formula of
c1v1 = c2v2
c = concn
v = volume
0.4M x ? = 8M x 50 mL
Solve for ? mL
By the way, I think the accepted IUPAC name for HBr is hydrogen bromide.
The mono is unnecessary.

To find out how many milliliters of a certain concentration solution can be made, we can use the dilution formula:
C1V1 = C2V2
where:
C1 = initial concentration of solution 1 (8M in this case)
V1 = initial volume of solution 1 (50mL in this case)
C2 = final concentration of solution 2 (0.400M in this case)
V2 = final volume of solution 2 (the one we need to calculate)
Let's plug in the values we have:
(8M)(50mL) = (0.400M)(V2)
To solve for V2, rearrange the equation:
V2 = (8M)(50mL) / (0.400M)
Now, we can calculate V2:
V2 = (400M·mL) / (0.400M)
V2 = 1000 mL
Therefore, 1000 mL (or 1 liter) of 0.400M hydrogen Monobromide solution can be made from 50 mL of 8M hydrogen Monobromide solution.
