Answer:
63.6 dm³
Explanation:
Volume of gas= no. of moles ×24dm³
Thus, volume of N₂O
= 2.65 × 24
= 63.6 dm³
Complete Question
49.9 ml of a 0.00292 m stock solution of a certain dye is diluted to 1.00 L. the diluted solution has an absorbance of 0.600. what is the molar absorptivity coefficient of the dye
Answer:
The value is
Explanation:
From the question we are told that
The volume of the stock solution is
The concentration of the stock solution is 
The volume of the diluted solution is 
The absorbance is 
Generally the from the titration equation we have that

=> 
=> 
Generally from Beer's law we have that

=> 
Here l is the length who value is 1 cm because the unit of molar absorptivity coefficient of the dye is 
So
=>
Answer:
C. Mole
Explanation:
Chemical formula deals with mole number
The answer is C. 7.30 x 10^-7
It is important to determine the qcalorimeter before determining the qmetal because the qcalorimeter is a constant and it's value is used to find the value of qmetal.
