Question

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.

    Answer:

    1.8 × 10^29 kg

    Explanation:

    The computation of the total mass is shown below;

    As we know that

    The total mass of the sun is

    = 2 × 10^30 kg

    Since 70% of the mass involves hydrogen gas, so total mass of the hydrogen gas is

    = 70% × 2 × 10^30 kg

    = 1.4 × 10^30 kg

    And, 13% available for fusion, so the hydrogen gas mass is

    = 13% × 1.4 × 10^30 kg

    = 1.8 × 10^29 kg
