My new apartment has no 3 prong plugs with ground

Speak to landlord to go with the building CODE and to replace/rewire them ALL at once. Calling building inspector once in a while will stimulate the landlord's speed of action.

Pre-war 2-prong wireing imposes a danger of setting building on fire and needs to be rewired new. Any tenant ringing a bell should not be neglected weather landlord loves or hates such. No matter how many amps you've got you may only use it OK for small appliances and microwaves, iron, corded drills may easily set these old wires on fire.
