Question

1. If one mole of carbon atoms
weighs 12 grams, what is the
mass (in grams) of 1 atom of
carbon?
2. Which has more number of
atoms, 100 grams of sodium or
100 grams of iron (given, atomic
mass of Na = 23 u, Fe = 56 u)?.​

Answer 1

Answer:

Atomic mass of carbon = 12u. But Atomic mas of carbon = 12 g mass of 6.022 × 1023 carbon atoms = 12g. = 1.9926 x 10-23 gm.
