If your requirement is to remove multiple spaces too, try this:

Select length('500  text Oracle Parkway Redwood Shores CA') - length(REGEXP_REPLACE('500  text Oracle Parkway Redwood Shores CA',
'( ){1,}', ''))  NumbofWords
from dual;

Since I have used the dual table you can test this directly in your own development environment.
