Final answer:

The conversion of 32 psi to g/cm^2 results in 220.63 g/cm^2, which differs from the options provided in the question. There may be a typo or mistake in the question as none of the given answers correspond to the correct calculation.

Step-by-step explanation:

The question involves converting the pressure from pounds per square inch (psi) to grams per square centimeter (g/cm2). To convert 32 psi to g/cm2, we can use the following conversion factors: 1 psi = 6894.76 Pascals (Pa), 1 Pa = 10 g/m2, and there are 10,000 cm2 in 1 m2. Converting 32 psi to Pa gives us 32 psi * 6894.76 Pa/psi = 220630.32 Pa. Now we convert to g/cm2, taking into account that 1 Pa = 10 g/m2, so we have 220630.32 Pa * 10 g/m2/Pa = 2206303.2 g/m2. Since there are 10,000 cm2 in 1 m2, we divide by 10,000 to find the pressure in g/cm2: 2206303.2 g/m2 / 10,000 cm2/m2 = 220.63032 g/cm2, which is not an option provided in the question.
