Amount remaining = (original amount) x (2)^-(years/1660)
Amount remaining = (200) x (2)^-(500/1660)
= (200) x (2)^-(0.3012)
= (200) x (0.8116) = 162.3 grams (rounded)
After 500 years, approximately 162.3 grams of radium will remain from an initial amount of 200 grams. This calculation is based on the half-life of radium, which is 1660 years. The process involves determining the number of half-lives that occur within 500 years and applying the decay formula.
