Answer
The molecular compound is $N_{2}O$
Work Step by Step
The atomic mass unit (amu) for the compound $N_{2}O$ is roughly 44.00 amu because (2∗14.00+16=44) which closely matches the atomic mass of the compound given in the question (44.02 amu) and since the compound only contains nitrogen and oxygen as stated in the question, the only possibility is dinitogen oxide $(N_{2}O)$.
