Conversions in Chemistry.? - scuba fill in station calculator
1. A radio presenter reports of air pressure 99.6 kPa. What is the pressure in atmospheres? In millimeters of mercury?
2. The reading of a barometer of the pressure 742 mm Hg Express this reading in kilopascals, kPa.
3. The analysis shows an air sample containing 3.5 x 10 ^ -6 psi of carbon monoxide. Express the concentration of carbon monoxide in Torr.
4. The pressure reading of the barometer is 540 mm Hg Express this reading in the atmosphere.
5. A balloon has a pressure of 15 atmospheres. Calculate the amount of pressure in millimeters of mercury.
6. Pascal Convert to 620 atm.
7. The pressure reading is a barometer for 567 Pa. Calculate the pressure in millimeters of mercury.
8. At 150 kPa is enclosed in a container. Expression of the pressure in Torr.
9. A dip tank is filled with air to 16.7 bar at 24 ° C. Calculate the pressure in millimeters of mercury.
10. A gasoline tank has a pressure of 20 atm. When power is applied, reducing half of its original pressure. What will the new pressure in Torr? Calculatethe final pressure in mmHg.
** I have determined for certain. Questions, but I'm not sure. Please help me. I need solutions and answers. Thank you very much. :)

Scuba Fill In Station Calculator Conversions In Chemistry.?

Let us first:
These are the conversion factors:
1 atm = 760 mmHg = 101.3 kPa
The first question for the pressure in atmospheres, are given. Because it is at 1 atm 101.3 kPa, convert given as follows:
99.6 kPa * 1 atm / 101.3 kPa = 0.983 atm
When converted to dimensional analysis in order to cancel the unwanted units. Please submit the above known and unknown in the background.
Note that 1 atm = 760 mmHg and 1 atm = 101.3 kPa
First, we must convert kPa ATM. MmHg after his conversion to the ATM.
99.6 kPa * 1 atm / 101.3 kPa * 760 mm Hg / 1 atm = 747 mmHg
