The unwritten rule is 1 -1 1/2 lbs per gallon(also depends how porous).

1.5 to 2 lbs. The more porous the better.

The general rule depends on the type of rock...some of the stuff from the Caribbean and some of the "base rock" that is sold is quite dense and honestly does not lend it self all that well to being used as live rock which has it's true use defined as biological filtration. I've run tanks with really good super porous rock at only about .75 lbs of rock per gallon with no issues at all. I actually prefer less rock so I can aquascape and keep some open area in the tank.

I've tried everything you can imagine in 20+ years...I don't like to promote taking rock off the living reef...especially if you've ever seen how much waste there is...that aside, I've yet to find anything that compares to true reef collected rock...I've used lace rock, lava rock, some of the dry rocks marketed by various folks today...none of it compares to the internal structure of micro pores found in the real deal.
