Answer:
165.52 g/mol
Explanation:
As the temperature raised to 100 C, part of the initial mass of liquid converted to gas, specifically 2.00-0.581 = 1.419 g. This gas occupies a volume of around 265 mL, at a pressure of 752 mm Hg and a temperature of 100 C. Assuming this gas behaves ideally, we can estimate its molecular weight 
using the ideal gas law:
with R= 0.082 atm L/(mol K)
or 
Before applying the formula, we convert volume to L (1L=1000 mL), pressure to atm (1 atm=760 mmHg), and temperature to K (K=273+C).
Ultimately, inserting values into the formula gives
g/mol
Response:
Each molecule consists of one carbon atom.
9.837 * 10^24 molecules correspond to 9.837 * 10^24 carbon atoms.
It's a 1:1 relationship.
Response:1816.6 joules
Clarification:refer to the attached image
To determine the answer, you need to understand the formula for converting grams to moles, which will then lead you to the number of molecules.
The result is 2 moles of N2O5. The process is as follows:
(0.25 g N2O5) (1 mol/ 108 g)=2.31 molecules
Thus, the final answer is 2 molecules.
Response:
The cuvette was prepared with the solution so that the spectrometer measures solely the absorbance from the solute. This also means the spectrometer disregards other fluctuations in absorbance that typically arise from the composition of water. The spectrometer focused only on the absorbance of 
as reflected in the spectrum. The reaction between the 
and the 
produces two clear liquids that generate the orange product which leads to the absorbance spectrum. Due to the orange color of the solution, it reflects this hue and others like it, while absorbing blue tones. To isolate the absorption of just the , pre-rinsing the cuvette with the solutions intended for measurement is advisable, along with using a kimwipe to clean any fingerprints that might impact data collection.
