Thanks for posting. A 6 lb spring weight is what you're looking for. If you're uncertain about what coil spring Series you need, let us see your pivot shoe removed from the window. The identity of the pivot shoe lets us identify the coil spring. Many thanks.

Ah, okay. Sounds like you need an S152-6, then. If you wanted to be 100% sure, though, then you can always weigh your sash on a scale and divide the weight between how many springs are used to support it. So if you use two springs to support this sash and its weight is 12 pounds, then you'll know for sure that you want the 6 pound spring.
