Expert Answer:

Unified mass unit : 1 u = 1.66 × 10-27 kg 
 
Hence,
 
fraction numerator 9.1 space x space 10 to the power of negative 31 end exponent over denominator 1.66 space x space 10 to the power of negative 27 end exponent end fraction space space equals space 5.48 space x space 10 to the power of negative 4 end exponent space u
