Question

A medical laboratory catalog describes the pressure in a cylinder of a gas as 14.82 MPa. What is the pressure of this gas in atmospheres and torr?

a) 149 atm, 1.51 × 10^7 torr
b) 14.82 atm, 1.51 × 10^7 torr
c) 149 atm, 1.51 × 10^5 torr
d) 14.82 atm, 1.51 × 10^5 torr

Answer 1

The pressure of the gas is 14.82 atm and 1.51 × 10^5 torr. So, the correct option is d).

Step-by-step explanation:

To convert the pressure of the gas from MPa to atmospheres (atm), we can use the conversion factor of 1 MPa = 9.87 atm. By multiplying the given pressure of 14.82 MPa by the conversion factor, we get 146.1654 atm. Therefore, the pressure of the gas is approximately 14.82 atm.

To convert the pressure of the gas from MPa to torr, we can use the conversion factor of 1 MPa = 7.5 x 10^3 torr. By multiplying the given pressure of 14.82 MPa by the conversion factor, we get 111150 torr. Therefore, the pressure of the gas is approximately 1.11 × 10^5 torr. So, the correct option is d) 14.82 atm, 1.51 × 10^5 torr.
