Vanity top+sink

My over 30 year old sink is leaking I went through the Home Depot’s vanity top+ sink inventory and found a product that matches my current vanity top dimension. My 40-odd year condo came with a stone countertop and the one I saw at the Home Depot website is a “D quartz” Vanity top that is pricey at around $600 and I the product specs say it is 130 lbs.

I have no idea how heavy my current vanity top+sink is, I just hope my current vanity table should be able to hold up to it. Would that new 130 lb vanity top+ sink be considered too heavy or just a regular weight for its size (28 x 22 square inch) ? Would like to hear fellow redditors’ insights. Appreciate it in advance.
