To what volume must 10ml of 5M HCl be diluted to make a 0.5M HCl solution......????
A.1ml
B.50ml
C.100ml
D.500ml
E.1000ml
C.100ml
To find the volume to which the 10 ml of 5M HCl solution should be diluted to obtain a 0.5M HCl solution, we can use the dilution formula:
C1V1 = C2V2
Where:
C1 = initial concentration of the solution
V1 = initial volume of the solution
C2 = final concentration of the solution
V2 = final volume of the solution
In this case:
C1 = 5M
V1 = 10ml
C2 = 0.5M
Now we can rearrange the formula to solve for V2:
V2 = (C1 * V1) / C2
V2 = (5M * 10ml) / 0.5M
V2 = 50ml
Therefore, the correct option is B. 50ml.
(Molarity x Volume)conc. = (Molarity) x Volume)dilute
Substitute and solve for Volume of diluted solution.
