My Swap space is currently set to 2 GB. How do I increase it?
Also I'm running with an SSD and have 16GB of RAM. What is the Max Memory I can set the swap file to?

Ubuntu 17.10 has reached EOL on July 19,2018. Please upgrade to a supported version, eg. 18.04 for continuous support. – Kulfy Aug 17 '18 at 18:43

- This should be closed as duplicate 2) With 16 GB of RAM it's more than enough even for chrome. 3) Consider trying ramdisk for chrome instead , see https://askubuntu.com/q/794290/295286

OK - That was a lot less scary than I thought it was going to be. I increased the swap size to 8 GB with the following sequence (Based on the 3rd answer in the linked post - Note that I had to turn off swap first - If you look at your system monitor you will see Ubuntu emptying out your swap space as you run the first command):
sudo swapoff /swapfile
sudo fallocate -l 8G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
Verify it:
sudo swapon --show
Make it permanent:
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
Update
This worked great and my laptop stopped freezing due to memory hogging by Chrome. One of the comments asserted that 16GB is enough, and in general I agree, but this is what my situation looks like:
