Final answer:
The estimated lifespan for large mass stars is 10 million years.
Step-by-step explanation:
The estimated lifespan for large mass stars is 10 million years. These stars are much more massive than our Sun and have a high rate of nuclear fusion reactions in their cores, which leads to a shorter life span. One example of a large mass star is Betelgeuse, which is expected to end its life in a supernova explosion.
