One mole of a substance contains 6.02×10∧23 particles,
1 mole of a aluminium contains 27 g
35 g of aluminium contains 35/27 =1.296 moles
 Thus, the number of particles will be 1.296 × 6.02 ×10∧23
      = 7.804 × 10∧23 particles,
Hence, 35 g of Aluminium contains 7.804 × 10∧23 atoms

What is the average atomic mass of the following isotopic mixture - 42.10 g/mole- 93.50%; 48.30 g/mole 6.200%; 50.40 g/mole - 0.
bazaltina [42]

Answer:

40.03g/mole

Explanation:

Given parameters:

Mass =  42.10 g/mole and abundance  = 93.50%

Mass = 8.30 g/mole and abundance =  6.200%

Mass  = 50.40 g/mole and abundace  = 0.3000%

Find;

Average atomic mass = ?

Solution:

Average atomic mass = sum (mass x abundance)

 Average atomic mass = (\frac{93.50}{100}  x 42.1) + (\frac{6.2}{100} x 8.3) + (\frac{0.3}{100} x 50.4)

                                      = 39.36g/mole + 0.52g/mole + 0.15g/mole

                                      = 40.03g/mole
