What is the approximate maximum mass a white dwarf can have before collapsing catastrophically?

Answer

The Chandrasekhar limit, approximately $1.4 M_{\odot}$

The structural integrity of a white dwarf is limited by the Chandrasekhar limit, established at about 1.4 solar masses. Exceeding this mass causes gravity to overcome electron degeneracy pressure.
