how much ram can an HP 14-df0xxx laptop take?

check the exact model before buying anything. a lot of the 14-df0 series have the 4GB soldered on the board with no slot, the giveaway is the word onboard in the memory line of the spec sheet for your exact number, and the HP maintenance and service guide for the model says it outright. if yours is one of those, no upgrade possible, and the realistic fix for chrome is fewer tabs, a lighter browser, or spending the money on a different laptop. if it does have a slot it's a DDR4 SODIMM, match the speed listed.
