Carbon dating is one of the methods used to determine the age of an artifact by determining the amount of Carbon-14 remains and comparing it to a living sample. A wooden artifact found in an ancient cave in Palawan contains 12 g of Carbon-14. If the same type, freshly cut wood, contains 32 g of Carbon-14, determine how old is the artifact. The half-life of Carbon-14 is 5,730 years. 5,896 years old 8,108 years old 9,975 years old 11,470 years old
