The word(s) "mortal" appears 48 time(s) in 45 verse(s) in Quran in Muhammad Pickthal translation.

(41) That was because their messengers (from Allah) kept coming unto them with clear proofs (of Allah's Sovereignty), but they said: Shall mere mortals guide us? So they disbelieved and turned away, and Allah was independent (of them). Allah is Absolute, Owner of Praise.

(42) This is naught else than speech of mortal man.

(43) We have appointed only angels to be wardens of the Fire, and their number have We made to be a stumbling-block for those who disbelieve; that those to whom the Scripture hath been given may have certainty, and that believers may increase in faith; and that those to whom the Scripture hath been given and believers may not doubt; and that those in whose hearts there is disease, and disbelievers, may say: What meaneth Allah by this similitude? Thus Allah sendeth astray whom He will, and whom He will He guideth. None knoweth the hosts of thy Lord save Him. This is naught else than a Reminder unto mortals.

(44) There wait on them immortal youths, whom, when thou seest, thou wouldst take for scattered pearls.

(45) He thinketh that his wealth will render him immortal.
