Mark wants to know how to connect a Neewer XLR mic to a laptop. Leo says that if it's a condenser mic, then it'll also need power. So an adapter won't really help. Leo recommends a Focus Rite Scarlet to power it and converter it to USB. However, some like the Newer XLR mic cannot work with Mac computers. That's only a $20 mic, and you'd be better off getting a USB compatible mic that works with any computer. If it's only for video conferencing, then Leo recommends the Blue Yeti or the Blue Snowball. It's decent. Samsung also makes a really good USB Mic called the Samsung Go.
