Question Is this the right ram for my laptop?

[JonathanTheGreater]

Hello! I'm planning on upgrading my ram from 8GB to 16GB, but I have no idea how this works!

I used the software from userbenchmark.com to obtain my ram information: (not sure if this is even accurate)
Samsung M471A5244CB0-CRC 2x4GB
2 of 4 slots used
8GB SODIMM DDR4 clocked @ 2400 MHz

So I found this pair of ram on ebay: https://www.ebay.com/itm/254421983915

Would this ram work? What should I look for when searching for ram?
