astrophysics - How to calculate the mean molecular weight of the Sun

I have a homework question in which I need to estimate a parameter known as $beta_{P}$ and also the core temperature, both for the Sun.



However, prior to doing this I need to know the mean molecular weight of the Sun.



First question is, how would I go about doing this.



Second question is, can I assume that it is about 70% hydrogen and 30% Helium?
