<u>Answer:</u> The initial volume of the gas is 16.55 mL
<u>Explanation:</u>
To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the initial volume of the gas is 16.55 mL
B. density is the right answer
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
The absorbance of the 214 mm solution of nickel(ii) chloride can be obtained by fitting it into the regression line of the calibration curve.
<h3>What is a calibration graph?</h3>
During measurements of the concentration of a solution using a spectrophotometer, it is conventional to first calibrate the instrument. The calibration is done by measuring the absorbance of various concentrations of the test solution after measuring the absorbance of the sample blank.
After the instrument has been calibrated, the absorbance of any test solution can now be obtained by fitting it into the regression line of the calibration curve.
