The explicit rule for this geometric sequence 29,23,2,6, is n = 29 × (29/23)^(n - 1)
<h3>How to write explicit rule</h3>
Second term, a×r = 23
23 = 29 × r
23 = 29r
r = 29/23
The explicit formula is given by
nth term = ar^(n - 1)
n = 29 × (29/23)^(n - 1)
Where,
nth term = number of terms

Answer:
4.13×10^22 atoms
Explanation:
1. Find number of moles
mole=mass/rmm of compound
mole= 3.50/102
mole= 7/204 mol
2. Multiply it with avagadros constant( 6.02×10^23 particles)
7/204 × 6.02×10^23= 2.0657×10^22
3. Multiply it with the number of ALMINIUM ATOMS IN AL203( which is 2 atoms)
2.0657×10^22 × 2
you get 4.13×10^22 atoms
