The Sun's chemical composition was about 70% hydrogen when it formed, and about 13% of this hydrogen was available for eventual fusion in the core. (The rest remains in layers of the Sun where the temperature is currently too low for fusion.)Use the given data to calculate the total mass of hydrogen available for fusion over the lifetime of the Sun. Express your answer to two significant figures and include the appropriate units. View Available Hint(s) for Part A Hint 1 for Part A. How to approach the problem Recall the mass of the Sun and note that 70 % of its mass is hydrogen, 13 % of which is available for fusion.
