Explanation:
SOLUTION:
Total amount of fruit = Total amount of apples + Total amount of pears + Total amount of oranges
Total amount of fruit = 15 / 4 + 29 / 4 + 81 / 8
Total amount of fruit = 30 / 8 + 58 / 8 + 81 / 8
Total amount of fruit = 169 / 8
Total amount of fruit = 21.125 kg
ANSWER:
Therefore, the chief bought 21.125 kg of fruit all together.

Hydrogen (H) has a molar mass of about 1.007 g/mol and has 1 electron.
Oxygen (O) has a molar mass of about 15.999 g/mol and has 8 electrons.
Then water (H₂O) has a total molar mass of about 18.015 g/mol and has 10 electrons.
30 g of water is the mass of
(30 g) × (1/18.015 mol/g) ≈ 1.66528 mol
of water. Recall that 1 mole is around 6.022 × 10²³ molecules (i.e. Avogadro's number). So 30 g of water is the mass of approximately 1.00285 × 10²⁴ molecules of water.
If each molecule contains 10 electrons, then 30 g of water contains 1.00285 × 10²⁵ ≈ 10²⁵ electrons.
