About three and a half glasses of rum. Not shots. Actual, normal, run-of-the-mill drinking glasses filled with rum. That makes it what, 0.5l*0.35=0.175l of pure alcohol when being conservative (especially since 0.375 is the minimum ABV and not 0.35) or about 0.7l*0.45=0.315l of pure alcohol when being generous. The real amount is probably around 250ml of raw alcohol.
