Cannot say. I bought it as a waterproof sealant and for this purpose it works perfectly.

Is this for 1 lb? Or for 10?

1 Lb. Was more than enough with plenty left over for other jobs

Can this be used to patch a hole in the wall around stove gas pipe?

Are you talking about a gas line coming into the stove, I’d say yes it can be. If you’re talking about the actual stove pipe that gets hot then no.

Would this work to fill a 2 inch hole with electrical wires coming through it that is immersed in hot water?

Yes, the only limit to this material is your wallet and imagination,
