why /'kɒŋgres/, not /'kɒŋres/?

[celtaflorida]

Greetings.
why is the word 'congress' pronounced /'kɒŋgres/, and not /'kɒŋres/? Might it be because of the nasal /n/ sound, and if so, when is the letter n not pronounced as nasal sound, when accompanied by g?
Also, do all gerunds and -ing (as in continuous forms,and adjectives) have nasal sounds without the g sound?
Thanks.

Some words, such as 'finger', always have the /ŋg/ sounds. Others, such as 'singer' in most varieties of English, just have the /ŋ/ sound. you just have to learn them as you meet them.

Also, do all gerunds and -ing (as in continuous forms,and adjectives) have nasal sounds without the g sound?

Yes, in most varieties of English.
