calculation og and dry hopping?

[allanyork]

Trying to figure out what my original gravity might be. I have mangrove jacks pilsner in the bag. Its liquid malt extract(2.2 kg) and I also have 1.3 kg of lme light. How can I calculate the og in a 23 litre batch?
Also should I use hops? I was thinking dry hopping saz. 2 oz?

I used this website to calculate og:

It came out to be 1.098, that seems high?

Estimated Pre Boil OG:
1.039
Estimated Original Gravity:
1.044
Estimated Final Gravity:
1.012
Estimated Alcohol By Volume:
4.20%


Ok this is what I get now. It was KGS when I thought it was lbs.

So this sounds really low now...
