As a rule, how much extra dry ice should I put it to match roughly the correct weight? I've seen varying estimates of sublimination time of 50% every 2 hours or 1% every 2 hours in insulated conditions.

Say for a given 500g item with a dry ice delivery in the morning at 9am and drop off at 1pm (4hrs) with an ambient temperature of around 10c, what would be the rough weight of the dry ice necessary to spoof 500g?

Thanks

with an ambient temperature of around 10c

Is that Fahrenheit or Celsius?
