To convert from pounds per square inch (psi) to kilopascals (kPa), we need to use the conversion factor 1 psi = 6.895 kPa. Therefore, we have:

11.0 psi * 6.895 kPa/1 psi = 75.8 kPa

To round to two significant figures, we get:

75.8 kPa ≈ 76 kPa

Therefore, the answer is B: 11eaa8f0_6706_d5e3_93a6_eb0468b35a95_TB6423_11 11eaa8f0_6706_d5e4_93a6_e35e0afa8bbf_TB6423_11.
