W-187 is a radioactive isotope that has a half-life of 1 day. Suppose you start with a 100-mg sample. What is the equation: y=100(1/2)^x (x- represents days) How would I find how long it would take for the amount of w-187 to decay to 5% of its initial amount?

Naturally occurring isotopes Problem #8: At time zero, there are 10.0 grams of W-187. If the half-life is 23.9 hours, how much will be present at the end of one day? Two days? Seven days?

W-187 is a radioactive isotope that has a half-life of 1 day. Suppose you start with a 100-mg sample. What is the equation: y=100(1/2)^x (x- represents days) How would I find how long it would take for the amount of w-187 to decay to 5% of its initial amount? Due to the short half-life of 187 W (t 1/2 = 23.7 d), the σ 0 for 187 W was obtained empirically by comparing the 188 W experimental yields with the theoretical yields generated by code IsoChain and varying the 187 W cross section while keeping all other parameters constant.
