Answer:
Option A
A blank is measured to remove the signal caused by the cuvette walls and solvent
Explanation:
Spectrophotometer is an instrument for measuring the absorbance or transmittance of the liquid in terms of wave function. The blank solutions is used for calibration of spectrophotometer while the cuvette is the container where the liquid sample is taken in the spectrophotometer. The absorbance of blank solution is known as zero hence the name blank solution. Normally, a blank is is measured to eliminate signal caused by cuvette walls on solvent and results into the formation of solute peaks in the spectra.

Answer:
T'=92.70°C
Explanation:
To find the temperature of the gas you use the equation for ideal gases:
V: volume = 3000cm^3 = 3L
P: pressure = 1250mmHg; 1 mmHg = 0.001315 atm
n: number of moles
R: ideal gas constant = 0.082 atm.L/mol.K
T: temperature = 27°C = 300.15K
For the given values you firs calculate the number n of moles:
this values of moles must conserve when the other parameter change. Hence, you have V'=2L and P'=3atm. The new temperature is given by:
hence, T'=92.70°C
