Part a the sun produces energy via fusion. one of the fusion reactions that occurs in the sun is 411h→42he+201e how much energy in joules is released by the fusion of 2.58 g of hydrogen-1? express your answer to three significant figures and include the appropriate units. view available hint (s) δe = submit part b this question will be shown after you complete previous question (s). return to assignment provide feedback

The equation for the nuclear fusion reaction is,

4 ¹₁H → ₂⁴He + 2 ₁⁰e

Calculation of mass defect,

Δm = [mass of products - mass of reactants]

= 4 (1.00782) - [4.00260 + 2 (0.00054858) ]

= 0.0275828 g/mole

Given that,

Mass of Hydrogen-1 = 2.58 g

The no. of moles of ₁¹H = 2.58 g / 1.00782 = 2.56 moles

Therefore, the mass defect for 2.58 g of ₁¹H is,

= 2.56 moles * (0.0275828 g / 4) = 0.01765 x 10⁻³ kg

Energy for (0.01765 x 10⁻³ kg) is,

= (0.01765 x 10⁻³ kg) (3.0 x 10⁸) ² = 1.59 x 10¹² J
