Type the correct answer in each box. Use numerals instead of words. Express your answer as a decimal number. The isotope samarium-151 decays into europium-151, with a half-life of around 96.6 years. A rock contains 5 grams of samarium-151 when it reaches its closure
temperature, and it contains 0.625 grams when it is discovered,
The time since the rock reached its closure temperature is years. When the rock was discovered, it had grams of europium-151.
