Answer:
one atom of sodium has a mass of approximately 37.9968 x 10^-24 grams.
Step-by-step explanation:
The atomic mass of sodium is approximately 22.99 atomic mass units. To convert from atomic mass units to grams, we multiply by the conversion factor of 1.6605 x 10^-24 g/atomic mass unit:
mass (g) = 22.99 atomic mass units * (1.6605 x 10^-24 g/atomic mass unit) = 37.9968 x 10^-24 g
So one atom of sodium has a mass of approximately 37.9968 x 10^-24 grams.
