Radioactive Decay and Half-Life Calculation

In a particular experiment, researchers investigated the properties of radioactive isotopes in medical imaging. They discovered that the half-life of a specific isotope is approximately 10 hours. This means that after 10 hours, half of the original amount of the isotope would have decayed into its daughter product. Based on this information, what would be the remaining amount of the isotope after 30 hours, starting from an initial amount of 80 grams?
