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.
