Question

Pls help

Three gases are added to a single tan of the same size. The first gas is currently at 303.9kPa, the second at 1900tor and the third at 132.3PSI. To one
decimal place, what are the percentages for each gas of the total pressure in the tank?

Answer 1

See Explanation

Step-by-step explanation:

We must first convert the gas pressures to a common unit. I choose to convert all pressures to kiloPascal.

Since;

1 kilopascal = 7.501 torrs

X. =1900tor

X= 1900 × 1/7.501

X= 253.3 Kpa

Since 1 PSI =6.895 kilopascals

132.3PSI = 132.3 × 6.895/1

= 912.2 Kpa

Total pressure = 303.9kPa + 912.2 Kpa + 253.3 Kpa = 1468.8 kPa

For first gas;

303.9/1468.8 × 100 = 20.7%

For second gas;

912.2/1468.8 × 100 = 62.1%

For the third gas;

253.3/ 1468.8 × 100 = 17.2%
