RTFM: mount(8).

I'm not sure what your tring to do ultimately, but if you do RTFM you see:

mount /mountpoint -o remount,rw
do stuff
mount /mountpoint -o remount,ro

most flags can can be changed ....

If you want to do it on a filesystem that contains /etc (ie /etc/mtab is,
or will be, on a readonly fs), then you need the -n switch too.
