14.7lb/in²

Explanation:

This is a conversion problem from atm to pounds per square inch

Pressure is the combined force per unit area of substance on another.

Given pressure = 0.5atm

To solve this problem ;

Convert from atm to N/m² to pound per square inch

1 atm = 101325N/m²

0.5atm = 0.5 x 101325 = 50,662.5‬N/m²

now we need to convert to pound per square inch;

1N = 0.225lb

1m = 39.37in

Solving;

101325 N $x \frac{1}{m^{2} } x \frac{0.225lb}{1N } x \frac{m^{2} }{39.37in x 39.37in}$ = 14.7lb/in²
