The largest category of primary malignant brain tumors that arise from cells in the CNS are called <u>Gliomas</u>
A malignant brain tumor is a rapidly developing malignancy that can spread to the spine and other parts of the brain. According to their growth rate and propensity to recur after therapy, brain tumors are often rated from 1 to 4 based on their behavior. Grade 3 or 4 tumors are classified as malignant brain tumors, whereas grade 1 or 2 tumors are typically classified as benign or non-cancerous.
The majority of malignant brain tumors are secondary malignancies, meaning they first developed in another area of the body before spreading to the brain. Brain-originating tumors, or primary brain tumors, are those.

Molar mass of N2H4CO = 60 g/mol
Given that the relative atomic mass mass of each element is known, We discover that;
Percentage by mass of nitrogen = 28/60 * 100 = 46 .7%
percentage by mass of hydrogen = 4/60 * 100 = 6 67%
Percentage by mass of carbon = 12/60 * 100 = 20%
Percentage by mass of oxygen = 16/60 * 26.67%
Answer:
