The amount of silicon-32 remaining after 900 years can be calculated using the formula for exponential decay, $A = P(1/2)^{t/T}$, where $A$ is the amount remaining, $P$ is the initial amount, $t$ is the time elapsed, and $T$ is the half-life. Substituting the given values, $A = 100(1/2)^{900/710}$, we find $A \approx 41.535$ grams.
