A can of coke contains 25 mL of carbon dioxide gas at 100kPa. If you take it on a hike up Mount Everest and the pressure decreas
Mazyrski [523]

Answer:

50 mL

Explanation:

We can solve this problem by using Boyle's Law, which states that:

"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"

Mathematically:

p\propto \frac{1}{V}

where

p is the pressure of the gas

V is the volume of the gas

The equation can be rewritten as

p_1 V_1 = p_2 V_2

where in this problem:

p_1 = 100 kPa is the initial pressure of the gas in the coke

V_1=25 mL is the initial volume

p_2=50 kPa is the final pressure

Solving for V2, we find the final volume:

V_2=\frac{p_1 V_1}{p_2}=\frac{(100)(25)}{50}=50 mL

Suppose you measure the absorbance of a yellow dye solution in a 1.00 cm cuvette. The absorbance of the solution at 427 nm is 0.
Dimas [21]

Answer:

The concentration of the solution, C=7.2992\times 10^{-6} M

Explanation:

The absorbance of a solution can be calculated by Beer-Lambert's law as:

A=\varepsilon Cl

Where,  

A is the absorbance  of the solution

ɛ is the molar absorption coefficient (L.mol^{-1}.cm^{-1})

C is the concentration (mol^{-1}.L^{-1})

l is the path length of the cell in which sample is taken (cm)

Given,

A = 0.20

ɛ = 27400 M^{-1}.cm^{-1}

l = 1 cm

Applying in the above formula for the calculation of concentration as:

A=\varepsilon Cl

0.20= 27400\times C\times 1

C = \frac{0.20}{27400\times 1} M

So , concentration is:

C=7.2992\times 10^{-6} M
