Oxygen flows through one tube into a liter flask filled with air, and the mixture of oxygen and air (considered well stirred) es
yKpoI14uk [10]

The amount of oxygen in the flask through the intake tube illustrates proportions

The flask 99.35% will contain of oxygen after 5L have passed through the intake tube

<h3>How to calculate the percentage of oxygen?</h3>

To do this, we make use of the following representations

  • P for the proportion of oxygen
  • V for te volume of oxygen
  • x for the proportion of oxygen in the flask after 5 L passed through

So. we have the following derivative

dP = dV - P * dV

Divide through by dV

dP/dV  = 1 - P

Next, we set up the integral

\int\limits^x_{0.040}  \frac {1}{1 - P}dP= \int\limits^5_0 {dV}

Integrate both sides

-\ln(|P - 1|)|\limits^x_{0.04} = 5

Expand

-ln(|x - 1|) + ln(|0.04 - 1|) = 5

Evaluate the difference

-ln(|x - 1|) + ln(|-0.96|) = 5

Express as a fraction

ln(0.96/|x - 1|) = 5

Express both sides as exponents with a base of 2

e^ln(0.96/|x - 1|) = e^5

Solve for x

x = 1 - 0.96/e^5

Evaluate the difference

x = 0.9935

Express as percentage

x = 99.35%

Hence, the flask 99.35% will contain of oxygen after 5L have passed through the intake tube

What is a cube in math
DerKrebs [107]

Answer:

In arithmetic and algebra, the cube of a number n is its third power, that is, the result of multiplying three instances of n together. The cube is also the number multiplied by its square: n3 = n × n2 = n × n × n.
