A tank of oxygen is under a pressure of about 4.00 x 10^3 kPa. Express this pressure in millimeters of mercury.

101.325 kPa = 760 mm Hg

Why did the oxygen go to therapy? Because it was under a lot of pressure, about 4.00 x 10^3 kPa! Now, let me convert that for you. In millimeters of mercury, the pressure would be approximately 3.00 x 10^4 mmHg. It looks like that oxygen tank needs a bit of a breather!

To convert the pressure from kilopascals (kPa) to millimeters of mercury (mmHg), we can use the following conversion factor:

1 kPa = 7.50062 mmHg

Given that the pressure is 4.00 x 10^3 kPa, we can use this conversion factor to find the equivalent pressure in mmHg by multiplying:

4.00 x 10^3 kPa * 7.50062 mmHg/kPa = 30,002.48 mmHg

Therefore, the pressure of the tank of oxygen is approximately 30,002.48 mmHg.

To convert the pressure from kilopascals (kPa) to millimeters of mercury (mmHg), we need to use the following conversion factor:

1 kPa = 7.50062 mmHg

We can apply this conversion factor to the given pressure of 4.00 x 10^3 kPa:

Pressure (mmHg) = Pressure (kPa) * Conversion factor

So, let's calculate the pressure in millimeters of mercury:

Pressure (mmHg) = 4.00 x 10^3 kPa * 7.50062 mmHg/kPa

To simplify the calculation, we can use scientific notation:

Pressure (mmHg) = 4.00 x 10^3 * 7.50062 x 10^0 mmHg

Multiplying the numbers and adding the exponents:

Pressure (mmHg) = 30.00248 x 10^3 x 10^0 mmHg

Remember that multiplying exponential terms involves adding their exponents:

Pressure (mmHg) = 30.00248 x 10^(3 + 0) mmHg

Simplifying the exponent:

Pressure (mmHg) = 30.00248 x 10^3 mmHg

Since 10 to the power of 3 (10^3) is equal to 1000, we can rewrite the pressure as:

Pressure (mmHg) = 30,002.48 mmHg

Therefore, the pressure of the oxygen tank is approximately 30,002.48 mmHg.
