Explanation

「のも当然だ」 means 'it is only natural that...'. 「の」 turns an event or reaction into a noun, and then you say it is natural, anyone would do the same: 「毎日12時間も働かされているのだから、彼が会社を辞めたがるのも当然だ」 (He is made to work 12 hours a day, so it's natural that he wants to quit). 「も」 adds understanding or sympathy; 「のは当然だ」 is also fine.

Mixed up with

「〜のも当然だ」: you judge that this is only reasonable.

「〜わけだ」: a sudden 'now I see, no wonder': 「暑いわけだ、38度もある」 (No wonder it's hot, it's 38 degrees).

Forms: na-adjective + 「な」; noun + 「も当然だ」, as in 「それも当然だ」.
