Q1: N2 content in a urea sample was found to be only 42%. What is the actual urea content of the sample ? (molecular weight of urea = 60)A 80%
B 90%
C 95%
D 98%
ANS:B - 90% To find the actual urea content of the sample, we need to consider that the nitrogen content in urea (CO(NH2)2) is 46.65% by mass. Therefore, if the nitrogen content in the sample is 42%, we can calculate the proportion of urea in the sample. Let's denote:
