Answer:
SrCl2 is diluted to 0.357M
Step-by-step explanation:
A handy relationship for dilution questions such as this is:
M1*V1 = M2*V2
Where M1 and V2 are the Molarity and Volume of the initial state.
And M2 and V2 are the Molarity and Volume of the final state
Lets collect what we know:
M1 = 5.1M SrCl2
V1 = 3.5L
M2 = Unknown, X
V2 = 50L (!)
Lets rearrange the equation to solve for the unknown, M2:
M2 = (M1V1)/V2
Enter the data and cancel units where possible.
M2 = (M1V1)/V2
M2 = (5.1M)(3.5L)/(50L)
M2 = (5.1M)*(3.5/50) [M cancels]
M2 = (5.1M)*(0.070)
M2 = 0.357M
