In the balanced equation, it can be seen that 6 moles of NO are required to produce 5 moles of 11ea71d0_de42_625a_91e5_337002e526a1_TB6077_11. Therefore, using mole-to-mass conversion, we can calculate the mass of NO required to produce 145 g of 11ea71d0_de42_3b48_91e5_09475de6fb88_TB6077_11.

First, calculate the molar mass of 11ea71d0_de42_3b48_91e5_09475de6fb88_TB6077_11:
2(207.2) + 3(16.00) = 468.4 g/mol

Next, calculate the number of moles of 11ea71d0_de42_3b48_91e5_09475de6fb88_TB6077_11:
145 g / 468.4 g/mol = 0.309 moles

Since 6 moles of NO are required to produce 5 moles of 11ea71d0_de42_625a_91e5_337002e526a1_TB6077_11, we can set up a proportion to find the number of moles of NO required:
6/5 = x/0.309
x = 0.371 moles

Finally, calculate the mass of NO required:
0.371 moles x 30.01 g/mol = 11.13 g

Therefore, the answer is A) 186 g, which is the closest choice to 11.13 g, but not exact. This may be due to rounding errors or variation in the molar mass of NO used in the calculation.
