How many milliliters of 0.225 M NH4C2H3O2 are needed to make 750.0 mL of 0.1667 M NH4C2H3O2?

dilution formula
ok so did I do it right??
0.225(750.0)=0.1667(v)
168.75/0.1667=1012.3??
0.225(750.0)=0.1667(v)
168.75/0.1667=1012.3??
Isn't this the same as the above?
0.225 x mL = 0.1667 x 750 mL.
mL = ?
The problem asks for "how many mL of 0.225M must ......."
so you have the v (unknown) in the wrong place.
0.225 x mL = 0.1667 x 750 mL.
