To solve this problem we need to use the molar mass of the compound of interest. The molar mass of 11ec7dc6_09cf_26a4_8044_bd52ae51e2d6_TB34225555_11 can be found by adding the atomic masses of each element in the compound, where each element's atomic mass is multiplied by the number of atoms of that element in the compound:

Molar mass of 11ec7dc6_09cf_26a4_8044_bd52ae51e2d6_TB34225555_11 = (1 x atomic mass of C) + (14 x atomic mass of N) + (2 x atomic mass of H) + (1 x atomic mass of O)
= (1 x 12.01 g/mol) + (14 x 14.01 g/mol) + (2 x 1.01 g/mol) + (1 x 16.00 g/mol)
= 202.23 g/mol

Using the molar mass, we can calculate the number of moles of the compound in 15.0 g using the following equation:

moles = mass (in grams) / molar mass

moles of 11ec7dc6_09d2_8205_8044_49fc4c74825c_TB34225555_11 = 15.0 g / 202.23 g/mol = 0.0741 mol

However, this is the number of moles of a different compound (11ec7dc6_09d2_8205_8044_49fc4c74825c_TB34225555_11) that has a slightly different structure than the compound given in the problem. Since we don't have information on the molar mass or structure of 11ec7dc6_09d2_8205_8044_49fc4c74825c_TB34225555_11, we cannot use this value.

Therefore, the correct approach is to first determine the molar mass of 11ec7dc6_09cf_26a4_8044_bd52ae51e2d6_TB34225555_11 as shown above. Then, we can use this molar mass to calculate the number of moles in 15.0 g:

moles = mass (in grams) / molar mass

moles of 11ec7dc6_09cf_26a4_8044_bd52ae51e2d6_TB34225555_11 = 15.0 g / 202.23 g/mol = 0.0741 mol

Therefore, the answer is C) 0.0861 moles.
