Answer:

4.13×10^22 atoms

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

Suppose a new planet were discovered between Jupiter and Saturn. What can you infer about the length of the new planet's year?
Serggg [28]
You can infer that the planets year is longer than Jupiters, but still shorter than Saturn's year, so you can add up Jupiter's and Saturn's orbit and divide by 2 to get more information about this "new planet".
