Answer:
Na k
Explanation:

heres your answer mate...
Multiply 10.49 by 12.993. that should be it. 130 grams ish?
Answer:
424 mol
Explanation:
Step 1: Given data
Number of atoms of Neon: 2.55 × 10²⁶ atoms
Step 2: Calculate the number of moles corresponding to 2.55 × 10²⁶ atoms of Neon
In order to convert atoms into moles, we need a conversion factor, which is Avogadro's number: there are 6.02 × 10²³ atoms of Neon in 1 mole of atoms of Neon.
2.55 × 10²⁶ atoms × (1 mol/6.02 × 10²³ atoms) = 424 mol
