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
