Calculating FG after addition of concentrate without hydrometer sample?

[Sol_Om_On]

Like the title says, is there some simple way to just calculate what the FG will be after addition of juice concentrate to a cider that has finished fermenting, without taking a sample?

Let's say if I have 5 gallons of cider at SG 0.995 and want to add concentrate of SG 1.200 (I guess concentrate usually has a very high value?), can I calculate somehow how much concentrate I would have to add to get an FG of the finished blend of say 1.010?

Thanks!

The concentrate I use is 12 oz which has 174 grams of sugar. According to the spreadsheet I have, each can will boost the SG of a five gallon volume by .005

To bring your FG from .995 to 1.010 you will need three cans of concentrate.
