The chief by 3 3/4 kg of Apple's 7 1/4 kilograms of peers and 10 1/8 kilograms with orange about how many kilograms of fruit did
WARRIOR [948]

Total amount of fruit = 30 / 8 + 58 / 8 + 81 / 8

Total amount of fruit = 169 / 8

Total amount of fruit = 21.125 kg

Therefore, the chief bought 21.125 kg of fruit all together.

About how many electrons are in 30 grams of water (H2O)?
jarptica [38.1K]

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.
