If you had a 5 gram sample of lawrencium how much would remain in 30 minutes?

Lawrencium (Lr) is a synthetic element with a very short half-life, approximately 27 seconds for its most stable isotope, Lr-262. Given its rapid decay, after 30 minutes (or 1,800 seconds), nearly all of a 5 gram sample would have decayed, leaving only an infinitesimal amount—effectively close to zero grams. In practical terms, any measurable amount would be lost long before the 30-minute mark.
