    Answer:

    1.10^6 kg of mass per second

    Explanation:

    All energy lost by the sun comes from nuclear fusion.

    Sun loses energy at 2.5*10^{19}J per hour, that is 9*10^{22}J/s

    To find the mass lost by the sun in liberation of energy you use the famous Einstein’s equation:

    E=mc^2\\\\m=\frac{E}{c^2}=\frac{9*10^{22}}{(3*10^{8}m/s)^2}=1*10^6kg

    hence, the sun liberates 1.10^6 kg of mass per second
