Answer:
mass of sample, M = 1.2359g
mass of CO2, mCO2 = 2.241g
mass of H, mH = 0.0648g
Since the compound is an organic compound,
when organic cpd is combusted it releases CO2 and H2O and NO2.
i) Mass of C, mC = unknown
CO2 molar mass, MCO2 = 44g/mol
C molar mass, MC = 12g/mol
mC = mCO2 × MC
MCO2
mC = 2.241g × 12g of C
44g of CO2
mC = 0.61g of C
C% = 49.36%
ii) mass percent of N = 28.84% of N
mass of N, mN = unknown
NO2 molar mass, MNO2 = 46g/mol
N molar mass, MN = 14g/mol
mN% = mN
M
where, M is mass of the sample.
mN = mN% × M
mN = 28.84% × 1.2359g
mN = 0.356g
iii) mass of O, mO = unknown
mass of sample = mC + mN + mO + mH
1.2359g = 0.61g + 0.356g + mO + 0.0648g
mO = 1.2359g - 1.0308g
mO = 0.2051g
O% = 16.56%
H% = 5.24%
iv) Empirical formula,
Element | C | H | N | O |
% |49.36%|5.24%|28.84%|16.56% |
A. M| 12 | 2 | 14 | 16 |
|49.36/12| 5.24/2 | 28.84/14 | 16.56/1|
n= |C= 4.1 | H= 2.6 |N= 2.1 |O= 1|
A.R |C=4.1|H=2.6|N=2.1|O=1|
Simplest | 4 | 3 | 2 | 1|
ratio
C4H3N20 is the empirical formula.
n = number of moles and at A. R is atomic ratio and I divided by smallest number of moles.
A. M = atomic mass.

Answers
Answer:
A
Explanation:
Because it helps us understand
To provide detailed descriptions of the instruments used at the Maragha and Tabriz observatories. Therefore option A is correct.
The passage primarily focuses on describing the various instruments utilized in the Maragha and Tabriz observatories during the Ilkhanid period.
The author discusses the massive astrolabe, the azimuth quadrant, and the equatorial ring, providing detailed information about their construction and usage in astronomical observations.
While the passage may touch upon the achievements of Ilkhanid scientists, it does so in the context of showcasing the precision and innovation of the instruments.
The purpose of the passage is not to evaluate the importance of the discoveries or criticize Ghazan but rather to offer insights into the advanced astronomical tools developed during that historical era.
Therefore option A is correct.
