How many grams of a 250- g sample of thorium - 234 would remain after 40 days had passed?
2 answers
How many days would pass while 44 g of thorium -234 decayed to 4.4 g of thorium - 234?
k = 0.693/t1/2
ln(No/N) = kt
No = 44g
N = 4.4 g
k from above
solve for t.
ln(No/N) = kt
No = 44g
N = 4.4 g
k from above
solve for t.
