If 4.0L of a 4.7M SrCl2 solution is diluted to 45L , what is the molarity of the diluted solution?

Recall the formula
M1 * V1 = M2 * V2
where
M1 = initial concentration
M2 = final concentration
V1 = initial volume
V2 = final volume
Substituting,
4.7 * 4 = M2 * 45
M2 = 4.7 * 4 / 45
M2 = 0.418 M
Hope this helps :3
