    2. Now we are ready to calculate the mean molecular weight! Using Equation 7 (below and in your lecture notes), calculate μ for the IMO, Z = 0.02 model at the beginning of the main sequence. Use data from Table 1 for H, He and set everything heavier to be Z, the metallicity. You will need your estimate for the average atomic mass in your calculation. Assume 1) the gas is ionised, and 2) the composition in Table1 reflects the proto-solar composition. 3, How do you think the mean molecular weight μ varies inside the star as a function of radius at the beginning of the main sequence. Explain your answer From your notes, you can use the following equation to calculate the mean molecular weight X(j) fj Recall that f, is determined by the level of ionisation and ranges from (1, z, + 1) where zj is the proton number of element j
    Now we are ready to calculate the mean molecular weight! Using Equation 7 (below and in your lecture notes), calculate mu for the 1M , Z = 0.02 model at the beginning of the main sequence. Use data from Table 1 for H, He and set everything heavier to be Z, the metallicity. You will need your estimate for the average atomic mass in your calculation. Assume 1) the gas is ionised, and 2) the composition in Table 1 reflects the proto-solar composition. How do you think the mean molecular weight mu varies inside the star as a function of radius at the beginning of the main sequence. Explain your answer. From your notes, you can use the following equation to calculate the mean molecular weight: 1/mu = sigma X (j)/A_j f_j Recall that f_j is determined by the level of ionisation and ranges from (1, z_j + 1) where z_j is the proton number of element j.

    2. Now we are free to proportion the medium molecular influence! Using Equation 7 (under and in your dissertation notes), proportion μ control the IMO, Z = 0.02 mould at the preface of the ocean succession. Truth basis from Table 1 control H, He and be anything heavier to be Z, the metallicity. You procure scarcity your prize control the middle ultimate bulk in your watchfulness. Assume 1) the exhalation is ionised, and 2) the mixture in Table1 reflects the proto-solar mixture. 3, How do you judge the medium molecular influence μ varies within the bigwig as a duty of radius at the preface of the ocean succession. Explain your repartee From your notes, you can truth the aftercited equation to proportion the medium molecular influence X(j) fj Recall that f, is stable by the smooth of ionisation and ranges from (1, z, + 1) where zj is the proton enumerate of atom j
