The prosecution's investigations revealed that the perpetrator killed the victim after she broke off the engagement due to her ex-fiancee's "excessive jealousy, controlling attitude and constant mistrust."
The decision can be appealed.
The prosecution presented as evidence during the trial a recording of a phone call at the time of the attack between Kholoud and a friend, whom Kholoud had called for help. In the call, the convicted man can be heard vowing to kill Kholoud.
Additionally, 18 witnesses who knew Kholoud testified that she had received threats from her ex-fiancee.
Another witness told the investigators that they saw the defendant enter the victim's home through the balcony on the night the murder took place, according to the investigation.
CCTV cameras in a building across from the victim's home show the perpetrator sneaking in and out of her building, it added.
Kholoud's murder is the latest in a recent string of killings of young women by men after they rejected them - cases which have caused public outcry and ended in death sentences for the perpetrators.
In August, a 20-year-old university student Salma Bahgat was killed in broad daylight in the lobby of a building in the city of Zagazig, the capital of Sharqiya governorate in the Nile Delta, after she and her family rejected the defendant's marriage offer.
In June, a similar incident stirred public anger when a 21-year-old student at the Faculty of Arts at Mansoura University killed his colleague Nayera Ashraf also in broad daylight after she rejected his proposal.
The perpetrators in these cases also received a death sentence.
