1 mole of NHSUB13UB0 weighs 306.35 g
1 mole of molecules of NHSUB13UB0 weighs 306.35 g

Therefore, 8.00 × 10^22 molecules of NHSUB13UB0 weighs (8.00 × 10^22 molec) x (306.35 g/mol) = 2.45280 x 10^25 g

To convert grams to kilograms, we will divide the value by 1000.

2.45280 x 10^25 g = 2.45280 x 10^22 kg

Thus, the mass of 8.00 × 10^22 molecules of NHSUB13UB0 is 2.45280 x 10^22 kg, which is closest to option C (2.26 g).
