A reading shows a pressure measurement of 43 in. Hg. What is the equivalent pressure in psi? A. 5.73 psi B. 2223.13 psi C. 26.32

oksian1 [2.3K]

43 inHg = 43 inHg*2.54cm/in = 109.22cmHg * 10 mm/cm = 1092.2 mmHg

14.7 psi = 760 mmHg

1092.2mmHg * 14.7psi / 760 mmHg = 21.13 psi

Answer: option D. 21.13 psi

A piston contains 5.00 L of gas at a pressure of 101 kPa. The piston is compressed until the gas occupies 2.00 L of space. What

galben [10]

Answer: 252.5 kPa

Explanation:

Given that:

initial volume of gas V1 = 5.00 L

initial pressure of gas P1 = 101 kPa.

new Volume V2 = 2.00 L

new pressure P2 = ?

Since, only pressure and volume are involved, apply the formula for Boyle's law

P1V1 = P2V2

101 kPa x 5.0L = P2 x 2.00L

505 = P2 x 2.00L

P2 = 505/2.00

P2 = 252.5 kPa

Thus, the new pressure of gas inside the piston is 252.5 kPa
